Changes and Shake-ups
----------
By now, everyone in the OS/2 community has heard that OS/2 Magazine, long running Miller Freeman publication, will cease publishing after January, 1997. There has been a lot of talk on the Internet regarding this news and its meaning. Some feel it proves that OS/2 is doomed, others maintain the news reflects only on the direction OS/2 Magazine had taken in the past year(s).
Those who know me are already aware of my opinions on OS/2 Magazine 's closure but for those who don't, let me say officially and personally I am very sad to see them go. While I obviously believe in the power of electronic media, I strongly believe that traditional print magazines bring unique and indisputable benefits to their readers.
Last month, I had the opportunity to discuss the closure with well known OS/2 Magazine REXX columnist, Dick Goran. When he heard the news that January's would be the last column he sent to OS/2 Magazine, Mr. Goran intended to include a "goodbye" message to his readers in his column. For various reasons though, that message will not make it in January's issue. So, to be even more timely, I offered to give him a forum here to say thank you to his readers:
"It has been my pleasure to write for OS/2 Magazine for the past three years. I'm sorry to say that this is my final column. Our (http://www.cfsrexx.com/) WWW site and (ftp://ftp.cfsrexx.com/pub/) FTP server will remain active. I will continue to post utilities as well as other REXX-related information there for all to access anonymously. My REXX and OS/2 advocacy will continue as will my REXX training and consulting. The new edition of our REXX Reference Summary Handbook, with all of the Warp Version 4 updates, is available and full details can be found on our Web site."
On a more positive note, one notable OS/2 software vendor has announced plans to jump into the print OS/2 magazine arena, and of course, there are still high quality OS/2 print magazines being published in languages other than English. Oh, and OS/2 e-Zine! has no intention of going off the air!
Since we're going to be around for some time, I spent a while last month playing with the browser that most of you will probably be viewing us with in the near future: Netscape and IBM's much needed second beta of Netscape Navigator 2.02 for OS/2.
While the newer version works much better than the original beta (the fact that it works is an improvement for some), it still doesn't thrill me.
Some time ago I wrote (http://www.haligonian.com/os2/v1n3/rant2.html) a Rant about how, although I liked WebEx, I wished for all the gee-whiz features of Netscape Navigator. Now that I have them, I'm wondering what this wish might cost me.
The new beta of Navigator, as I've said is a vast improvement over the initial beta but it still has a lot of little "features" that I'm not so sure are beta problems. Graphics and fonts don't seem to be displayed as crisply as with WebEx; the default borders around graphical links are not nearly as nice as WebEx's; the darn thing insists on redrawing each button on the button bar every time my screen redraws...
I suppose some of these things will turn out to be growing pains that will eventually be fixed but I'm starting to worry that I'll end up writing a Rant in a few months pining for the days when we only had to worry about how OS/2 e-Zine! displayed on good old WebEx.
Be careful what you wish for, I guess.
Despite my personal disappointments with Netscape's progress on their browser, I did have some good news last month. I was happy and relieved to hear that IBM, first in the US and then in Canada, has announced Academic pricing on OS/2 Warp 4.
This welcome news first came from the US when (http://www.indelible-blue.com/ib/) Indelible Blue announced that (through the efforts of OS/2 customers) IBM had acknowledged the demand for Warp 4 in Universities and Colleges. Indelible Blue started taking pre-orders and is now shipping Warp 4 Academic to qualified students, faculty and staff for US$85. This version does not include microphones but the new price has relieved many cash-starved students.
Not to be outdone, at the end of November, IBM Canada announced that by December 3rd they would also have an academic version of Warp 4 available. Like their US counterpart, they are shipping non - microphone - containing boxes but again the price is substantially less than the full version price. Canadian OS/2-only distributor (http://www.hotinc.com/) House of Technology expects it to hit the campuses in Canada (via H.O.T.'s distributors across the country) at around the Cdn$127 mark. We have no word yet whether IBM will spread this practice (or if they already have) in other countries.
IBM may not be overly interested in consumer-level marketing these days, but at least they still realize the value of grass-roots academic sales.

Chris' Rant - by Chris Wenham

Goodbye Yellow Brick Road
Close to the end of each month I enter a mild panic when I don't know what to write about in this column, and usually, at the end of each month, someone does something fabulously stupid and my writer's block goes away like magic.
Last year Sun gave us a new programming language and promised earnestly that true platform independent applications were but a few Software Development Kits away -- Java.
Last month Microsoft announced they were splitting their own version of Java away from the standard and making a compiler that would produce Windows-only Java binaries -- Excrement.
This is an act of stupidity and a stroke of genius rolled into one, if there ever could be such a thing. I'm sure Microsoft is giving itself a darn good pat on the back, running through the halls of Redmond campus shouting, "It's Unix all over again!" and contributing once again to the rape of an idea they were too dumb to think of themselves. But I also think they've not-so-intelligently created their own competitor to ActiveX, given developers one more API to deal with, and diversified their product line with something that can only possibly be called the fifth wheel of programming languages.
For crying out loud, if you're only going to develop for Windows anyway, why the heck not write it in C++ or Visual Basic?
Perhaps the Surgeon General can put a warning sticker on the new Microsoft Java packages; "Warning: useless to anybody unless compiled for platform independence."
It's my sincere hope that developers consider just exactly what the point of Java is. It's the Platform Independent nature of it that makes it more than just another ho-hum C wannabe and a momentary blip of a fad on the Internet radar screen. It's neither rocket science nor a carefully guarded secret that spawning off proprietary and incompatible versions of this language will make it as complex and out-of-reach for the average user as today's Unix systems are.
But a trend has been set by the biggest trendsetter of the industry, is it any surprise that companies like Borland, Silicon Graphics and others are either supporting it wholeheartedly or trying to pull off the same trick themselves?
I was skeptical and worried when IBM fell in love with Java so quickly and, to all outward appearances, seemed to be hinging OS/2's success on it as well. Now I'm more worried, because it seemed at first that we would all walk down a yellow brick road; we learn instead that Oz has a toll booth at its gates, and we all use the wrong currency to get in.

the Rave: Slice/2 & Splice/2 v1.00
----------
Long ago, in earlier days, there were two programs that came close to being as ubiquitous as Microsoft's (in)famous MS-DOS: PKZip and it's sister, PKUnzip. Long before the Internet was a mass market product, computer users eager to connect to others were filling up BBS discussion boards and file archives by the millions. And the compression software of choice for those DOS users was PKZip.
When OS/2 started gaining popularity outside the corporate world in the early nineties however, PKWare stumbled and fell (in the OS/2 world that is). While a native version of PKZip and PKUnzip were available for OS/2, they were not as feature rich as their DOS counterparts. More importantly, the nice people at Info-Zip went and created an alternative to the PKWare's products: Zip and Unzip for OS/2.
By now, if you're reading these words, you know that Info-Zip's free compression and decompression utilities are probably the most commonly used OS/2 software on the planet. These utilities are free and they work great, but they've always had one nagging problem -- unlike their DOS counterparts, they do not have the ability to spread a zipped file over more than one floppy disk. This feature is planned for a future release of Zip but there may be no need.
The reason there may be no need, is a simple, effective and brilliantly useful shareware utility called Slice/2 and its companion software, Splice/2.
Slice/2 is an old (circa 1992) command-line utility that does exactly what you would imagine: it takes a file and slices it up, storing it on multiple floppy disks, prompting you each time it fills one and needs another.
Splice/2 does the opposite: takes sliced files and reconstructs them on (presumably) your hard drive.
Both utilities do the job that Zip and Unzip fail to do. These programs are dead simple and tiny (each program is under 10K). You can even store sliced files on floppy disks containing other data. This means that the Slice/2 program uses every byte of storage on a floppy whether it is 1.44 MEG, 740K, or just a spare 20K. It's a dream come true for people with tons of smaller files and some larger ones they need to get off their hard drives. The utilities can even dissect and reconstruct files onto (or from) as many as 999 floppy disks (if you have a file that large).
If you are like many OS/2 users out there that have yet to upgrade to a Zip, EZ135 or higher capacity removable drive and you want to clean up the clutter on your hard disk, Slice/2 and Splice/2 are great ways to do so. Until Info-Zip gets around to updating Zip and Unzip to include such functionality, Slice/2 and Splice/2 are great solutions for anyone needing to stuff files onto archaic media.

the Rave: TransWarp PlusPak - by Thom Davis
----------
Did you ever wish someone would figure out how to write a program like Microsoft Plus for OS/2? Well, guess what -- someone has: The TransWarp PlusPak by KrazyDog Software. It's one of those "GEEZ WHIZ" type programs that we really don't need but are fun to play with.
Basically, the program uses "schemes" to spice up your Desktop. There are 20 or so schemes provided and you just have to pick which one you would like to change your Desktop too. There is a preview button with which you can examine the 20 or so schemes that the author, Michael Neice, has come up with (but it does take a while to load the previews as it uses OS/2's Image viewer).
As we all know, messing with your Desktop can be risky business and the author warns you to make a backup of your original Desktop before playing with the program, but me, being crazy, I tried it without backing mine up and it worked flawlessly.
Changing your Desktop background and the icons for several of the universal objects that come with Warp 4 is now much easier. No more having to open each object's properties menu and drag a new icon into its page, no more digging around looking for those icons and no more having play around with background images. TransWarp will do all those things!
The variety of schemes that the author has included is very broad, ranging from Star Trek, to Horror, to (dare I say it) Win'95. There is also an option to go back to the default OS/2 Warp 4 screens. The program is lacking a few things like "Sound Schemes" and a way to add your own themes, and it is slow to change themes, but considering how long it would take you to do it by hand, it's well worth it.
And it's just plain cool!
All in all, it is very well done and even uses customized pointers inside the program (which I personally had not seen done before). And with a little encouragement, I believe the author would be willing to dig deeper into it and put in the few things that could make it a dynamite answer to that other PlusPak.

OS/2 users looking for a new business management and accounting package, take heart. (http://www.erols.com/cybercom/cyber.html) Cybercom is currently working on and taking pre-orders for AccuCount/2, a new OS/2-only, 32 bit, multi-threaded, accounting program that handles invoicing, inventory, purchasing, G/L, P/L and much more. There is also a fully integrated Contact Manager that tracks all transactions, contacts and events in an easy to understand format. A payroll module and multiuser version are planned for release at a later date.
Late last month, Alpha testing was occurring at four major client sites and internally. Now, over 100 beta testers have signed up. Cybercom has just opened the beta test for new applicants and they would like to get as many as possible to fully use and abuse the program, provide feedback and bug reports. Have a look at their web page for more details, including a special Preview/Beta offer.
The final version of the product is due sometime between Q1 and Q2 1997 at a price of around US$125 and it will be distributed as commercial software. For even more information, check the Press Release on (http://www.software.ibm.com/os/warp/html2/pr/cybercom.htm) IBM's Software Home Page.

In addition to their ongoing beta test (to be released real soon now) of SmartSuite for OS/2, Lotus has also begun beta testing Lotus Domino for OS/2. Domino provides a powerful engine for communication and collaboration using standard Web browsers. It takes advantage of Lotus Notes technology and Warp Server SMP and is compatible with OS/2 Warp Connect and OS/2 Warp Version 4.
Lotus is conducting an open beta program and is still looking for participants so if you're interested you are welcome to sign up. The Domino 1.5 Beta 1 for OS/2 Warp is available for download from the (http://domino.lotus.com/) Domino home page.
This (obviously) commercial product from Lotus is expected before year end, 1996. Final pricing information is not available at this time but expect a single-processor server to cost about US$995, and a multiprocessor US$2995.
* * *
Stardock Systems, having recently wrapped up beta testing of both Process Commander and Trials of Battle (both of which should be shipping by the time you read this), is moving ahead with its beta test of Entrepreneur and is currently shipping Beta 4 to its "early experience" testers. The new beta is available on (http://www.stardock.com/) Stardock's web site (under the "software updates" link).
The economic strategy game will build on Stardock's long tradition of offering strategy games that focus on realistic struggles for dominance. Entrepreneur will be a multi-player, real time game playable over a network, the Internet or modem. Beta 4C introduces new features to the game such as a design screen, research screen, Artificial Intelligence, random world generation, and more. Graphics and sound in Entrepreneur will be provided via DIVE and DART for maximum quality.
While the game was first expected some time this year, it now looks like final ship date will be in the first quarter of '97. The game will sell as a commercial package through Stardock's normal channels. Expected price for non-early experience participants is US$59.95. Complete details and loads of screen shots are available at (http://www.stardock.com/ent.html) Stardock's Entrepreneur Page.
Entrepreneur will be available on the OS/2, Windows 95 or WindowsNT platforms. In a conversation with Brad Wardell, president of Stardock Systems, he commented that this is intended to help sales of both the OS/2 and non-OS/2 versions of the game. The reasoning used is that if a game is available only for OS/2, game magazines don't like to give it coverage in reviews. If it is a multiplatform game however, magazines review it and non-OS/2 users see that games are available for OS/2 as well as their platform of choice.
* * *
(heller1@ibm.net) Norbert Heller Software has recently announced a new version of its Media Player for OS/2, Albatros Media Player 2.0, and is accepting participants for its public beta test.
The purpose of Media Player 2.0 is to have a single player for all multimedia file formats instead of having a player for every file format as supplied in OS/2. Media Player should play the following file formats:
o MODule Formats (those "Amiga Thingies" -- see review in this issue)
o AVI (both OS/2 and Windows)
o MPEG 1 movies (with IBM's Openmpeg)
o Audio Mpeg Layer I + II (an encoder for WAV files is included)
o FLC / FLI
o WAV
o VOC
o MID
o QuickTime Movies (with an Additional QT Codec)
The beta test is public and is still open. The Media Player can be obtained from (ftp://ftp-os2.cdrom.com/os2/incoming/alb_mp_pb4.rar) Walnut Creek and feedback should be directed to Norbert Heller Software. While the software is in beta testing, it is shareware so registrations of US$25 are now being taken. For more information, see the (http://www.wilmington.net/bmtmicro/heller/) Heller Home Page.

And, of course, the second beta of Netscape Navigator for OS/2 was finally made available at the end of November. Aside from the (http://www.internet.ibm.com/browsers/netscape/warp/) default web site linked from the OS/2 Warp 4 Desktop, the file can be downloaded by FTP directly from:
(ftp://service2.boulder.ibm.com/software/netscape/nsos2_b2.exe) ftp://service2.boulder.ibm.com/software/netscape/nsos2_b2.exe; or
This release is the complete package; Netscape Navigator for OS/2 now features:
o Fully integrated browser, mail, news
o Mail with HTML mail support, address book etc.
o News reader
o Printing
o Drag and drop
o Voice support
o Bookmarks
o Clipboard support
o Secure site access
o Java 1.02 included in package (for Warp 3.0 and 4.0)
o Javascript
o OS/2 Multimedia plug-ins
o Support for Windows 3.1 plug-ins
o DDE interface
o Performance improvements and fixes
A word of warning, be sure to remove the first beta of Navigator before installing this second one. Also, be prepared to wait for the download; the archive contains the complete OS/2 Java code so it is over 5 megabytes.
As most OS/2 users now know, Netscape Navigator 2.02 for OS/2 is the joint project of IBM and Netscape Communications. It is free now and will remain free to OS/2 users and will run on Warp 4 or Warp 3. The final version of Navigator 2.02 is expected before the end of '96 but currently, no firm date can be determined.

----------
Q -- Presently I'm using Warp 3, and I'm debating upgrading to Warp 4. I have a lot of files from the Warp 3 BonusPak, like spreadsheets, data files and reports. Will they be compatible with Warp 4 or will I lose everything?
A -- The files from Warp 3 BonusPak seem to be completely compatible. We also have a few spreadsheets plus a todo list that we use constantly. All these items are now used regularly with Warp 4. We needed to make no modifications to them although we did have to manually copy the todo*.* files to the new OS/2 partition since we installed Warp 4 separately from Warp 3.)

Q -- I am using OS/2 Warp 4. I am also using both WebExplorer and Netscape for OS/2. Whenever I go to a page that has Java capabilities, or applets, I cannot view them. Could you tell me where or how I can get a Java enabled browser for OS/2?
A -- Netscape Navigator 2.02 for OS/2 is a Java capable browser. All you need to do to view Java applets in Navigator is click the "Options" menu and open the "Security preferences..." submenu. This will open a notebook that will have check boxes for enabling or disabling Java script or Java application support. Don't forget to make sure you have the latest version of Navigator 2.02 for OS/2 (beta 2 at the time of this writing). It contains the latest Java for OS/2 code (v1.02).

Q -- I have seen an "Artchron" task running on my Warp 4 system after booting but don't know what it's for. I have heard a few ways to get rid of it by renaming or deleting its files but would prefer something more "official". How do I keep it from loading?
A -- Open your boot drive from the Drives object (or WarpCenter) and look in the "OS2\INSTALL\Installed Features\" folder. There should be an "Install Object - Inventory" object there. (I'm not sure what it is called on a FAT system, sorry; hopefully from the WPS it will have the long names anyway.) Open it and put a check mark on "ART - Inventory" and click "Uninstall".
IBM has been playing with a new install/uninstall mechanism; from the looks of it, it could be rather interesting. (Try opening one of the Inventory objects to see what it looks like.)

Q -- We have an account with Easynet in the UK and we can connect using Win3.1, Win95, and PowerMac, but have failed to connect with Warp 3.0, Warp 3.0 Connect, Merlin Beta and Warp Server. I keep getting the message that the CHAP request failed. I tried InJoy and used a script to log in but nothing else happens. I don't seem to be able to ping any address and cannot, obviously, get anything on a Web browser. Is there documentation anywhere that could help me find out what I'm doing wrong?
A -- I cannot give a definitive answer to this question, but I have had
similar experiences (Windows works and OS/2 doesn't). My ISP would give a perfect connection with Win3.1 but OS/2 Warp, using the standard SlipPM.EXE, would not connect properly. I kept getting a connection, then instantly a dropped carrier, every time, regardless of traffic.
I found that the hardware was causing the problem for Warp. When I installed a short cable and took out my switch box, it worked fine.
There are two things I learned:
1. Assume nothing when tracing connect problems -- it could be hardware or software; and
2. OS/2 Warp still seems to have some problems with Internet connections when compared to Windows et al.

-----
Q -- I have Warp 4 and want to create boot disks which use the OAD.SYS driver so that my OS/2 session will access my Iomega drives (ZIP and Bernoulli).
I had little difficulty modifying my c:\config.sys to use the OAD driver. However, the procedure described in Iomega's texts for the creation of emergency boot disks, though it worked just fine under Warp 3, does not work under Warp 4.
The boot-disk-creation procedure involves modification of the first two of the three installation floppies. Has the structure of the installation floppies changed so that one cannot have an OS/2 session in two floppies? In Warp 4, the Iomega suggested disks result in the system still demanding insertion of disk 3 rather than an OS2 prompt.
A -- While it may technically be possible to fit a system in two disks, I do not know of anyone who has done it yet. Make the necessary modifications to the boot disks, but put the OAD drivers on disk 2, which is actually the third disk:
disk 0 (install disk), disk 1, disk 2 (OAD drivers).

Chris' ColorWorks PowerTips - by Chris Wenham
----------
Solar Lens Flares
Tip works in ColorWorks 2.0 or higher
A while back I picked up a comic book and looked over its cover. The cover was a pretty cheesy space-scene; what interested me was the sun-flare effect the artist had used. It had a white core, fading out to stellar red with a faint pink halo or shockwave. "I can do thaaaat!" I thought to myself, and after getting home I set about doing it with ColorWorks.
The effect is really just a radial gradient, using a red-to-white palette, inverted and with the opacity control switched on. My palette also has a custom gradient map to get the 'shockwave' or halo-ring at the fringes. You draw it onto a black/space background with the circle tool.
We start with a simple space scene with the shuttle floating high above the Earth's atmosphere, set against a thick black and featureless background. Next we set up the gradient, the trickiest part of this is to find a gradient map that's just right -- one that'll give us the tight white-hot core of the sun, fading out with a dim red, and concentrating again to form the pink lens-flare halo at the rim. This is the one I made, although you might want to fiddle with it some to get what you want in your picture (fiddling is an art form itself and probably the only one at which all human beings are equally inept).
The palette is easier to make though; it's just a spread from red to white (not white to red, since we'll be inverting it later to get the opacity setting we want). Then we just make sure the gradient is set to vary opacity and palette colors, is radial and set to 0% noise and no rotation. The Gradient dialog should look a bit like this one.
Simpler yet is to download the Graphics State file included later in this article, but that's cheating... right?
With everything set up we just select the circle tool, make sure it's filled, and draw a test flare on a plain black canvas. Ooops! A bit hard around the edges. Okay, so we go to Effects.Drawing Merge Control and set the blend-filled-edges to about 3 or 4 to smooth that out a bit. Now we try again on the space-scene canvas, first a small flare and then a bigger one.
You'll notice that on the small flare our 'shockwave' didn't really come out, but on the bigger one it did. We get the effect of a light shining directly into the camera lens and causing a faint pink halo.
Q & A Center
""Sometimes when I have a custom palette loaded I need to quickly grab a color from the default palette, but don't want to have to reload my custom palette all over again. Is there a way I can grab the color I want without loading the new palette over top of the old one?""
- Joe Anybody, Somewhere, Idano
Dear Joe, if you go to Palette.Load Palette... and pick the palette you want from the tabbed notebook, you'll find that the mouse will turn into an eyedropper when you hover it over the colors. Click on the color you want, then click on the Cancel button instead of the Load button. The new drawing color will be whatever you clicked on with the eyedropper and it won't replace the palette you already had loaded.

As I promised last month, I've pulled together a ton of new textures, palettes, graphics states and more. The gradient map, palette and graphics state for this month's tip is here, although you only really need to download the graphics state -- you can save the gradient map and palette separately if you wish.

Object Desktop Tips - by Alexander Antoniades
----------
Since its initial release, Stardock Systems' Object Desktop has been among the best selling OS/2 applications in the world. Many OS/2 users enjoy greater productivity thanks to Object Desktop's helpful features.
Something many Object Desktop users don't know, however, is that there are many undocumented or often overlooked features of Object Desktop that can make your OS/2 system even more productive and fun to use. We've gathered together a few of them to share with you.
Hidden Mouse/Keyboard Shortcuts
The following actions can be performed from anywhere within the Workplace Shell when Object Desktop is installed:
o Hold down the ALT key and double click on the status bar of any Workplace Shell folder and the settings notebook for that object will come up.
o Hold down the Ctrl and Shift keys while double clicking on a folder, and that folder will automatically enter browse mode in the parent folder's window. Note: this feature will not work when the parent folder is the Workplace Shell Desktop.
o Right double click on an object to bring up its settings notebook.
Checking your computer's pulse
One of the more popular parts of the Control Center of Object Desktop is the pulse meter that can explain CPU usage. While most people like its default appearance of two solid colors (selectable by drag and drop from any Workplace Shell color palette) some people like the style of the original OS/2 Pulse applet which is more like a hospital heart monitor.
You can make the CPU meter in the Control Center appear like a "hospital heart monitor" by opening the Control Center in either Object Package (which is in all versions of Object Desktop 1.5+) or the Object inspector (included in Object Desktop Professional) and changing the CPU_NOFILL= parameter in the Control Center from 0 to 1.
Restarting Object Desktop with the Workplace Shell
One of the complaints that people have made about Object Desktop is that when the Workplace Shell is restarted (either intentionally or by crashing) the enhancements from Object Desktop don't restart with the shell. And while you can manually restart most
of the components, such as Control Center and the Tab LaunchPad, others such as the Task Manager can't be restarted.
To make Object Desktop restart when the Workplace Shell is restarted, simply create a shadow of your Master Setup object on the Desktop and everything that you've selected to autostart will be restarted with the Workplace Shell.
This is necessary because of a Workplace Shell limitation regarding the reinitialization of Startup Folders. The Master Setup object is actually a subclass of the Startup folder and Startup folders are only initialized on boot-up unless they're on the Workplace Shell Desktop.
Undocumented CONFIG.SYS Calls
Many customers have been inquiring about different configuration options that can be changed in Object Desktop. Listed below are several undocumented environment variables that can be set in your CONFIG.SYS file to change particular behaviors of Object Desktop 1.5.
o SET OBJD_LOG=AUTO (Will write automatic trap logging to file: objdtrap.log when error occurs)
o SET OBJD_ALLVISIBLE=1 (Allows all invisible objects to be in Control Center browser objects)
o SET OBJD_NODISKASFOLDERS=1 (Allows all WPDisk objects in Control Center browser objects to be treated as 1.0 disk objects.)
o SET OBJD_DISABLEFASTMOVE=1 (Causes Control Center to change virtual Desktops using slow, safe method, to avoid FP16-FP18 multiple window position PMMERGE trap.
o SET OBJD_ONAVFULLMENUS=1 (Causes Object Navigator context menu to show move, copy, etc..)
o SET OBJD_URLNOPAINT=1 (Disables URL underline painting for Stardock Internet Shell Objects)
o SET OBJD_URLNOOPEN=1 (Disables URL open processing for Stardock Internet Shell Objects)
o SET OBJD_NOF12ROLLUP=1 (Disables Alt-F12 roll up accelerator)
Please remember to make a back up of your CONFIG.SYS file before making any changes.
That's it for this month. Next month we'll feature even more undocumented and useful tips and tricks for Object Desktop.

Hi and welcome to hell. My name is Jon, and I'll be your tour guide...
Seriously though, if you go shopping at this time of year, you find yourself hearing similar to that (or at least you'll hear those voices) from your local salesman. This month I had a nice article all planned out, but then I got a letter from the editor of this fine publication a few weeks ago. It seems a reader felt that by addressing the needs of 486 users looking to squeeze a little more life out of their machines, I was doing a disservice to those people with first generation Pentiums who need to get a little more life out of those machines.
He was right, you know. So this month I'll be talking about precisely what he suggested, which was: getting a little more life out of those first generation Pentium systems.
So that Pentium 60, 66, or 75 doesn't have half the punch it used to? Makes sense, considering clock speeds have doubled in the last short while. So is it useless? No more useless than a good 486-based system. There are a number of things you can do to bring your system up to date.
Before you begin: Memory, Memory, and more Memory. Seriously folks, I can't say it enough. A Pentium 75 with 24MB of memory will whip a Pentium 150 with 8MB of memory when running OS/2. And with prices so cheap, there's no excuse not to upgrade. I think I've mentioned this enough in the past, so I'm not going to harp on the subject. But you know where I stand.
Now, to business.
Processor
Upgrading the processor is a good option for these first (and second) generation Pentiums. Since the bus runs at the same speed as today's systems, the performance from an upgrade chip will generally bring your system up to the level of a brand new system (unlike the 486 Pentium upgrades). Depending on your preference and mood towards Intel, there are a number of viable upgrade paths for you.
If you have a....
Pentium 60/66. The earliest Pentium systems are those most in need of an upgrade.
The Intel Upgrade is...
The Pentium 120/133 upgrade. Generally runs about US$250 now, cheaper some places, more expensive in your local superstore.
If you have a....
Pentium 75. A solid second generation pentium chip, in most cases.
The Intel Upgrade is...
The Pentium 150 overdrive chip. Generally runs about the same as the 120/33 chip.
Or you could....
Evergreen makes an upgrade chip that upgrades the system to a 686/100. Performance will not be in the same ballpark as the Intel overdrive.
At this point, you may be wondering about the Cyrix 6x86 chips. As a general rule, the BIOS in your system has to support the Cyrix chip. If you don't know if your BIOS supports the Cyrix chip, find out. And, if it's a system you bought at a local superstore (Best Buy, Sears, CompUSA, etc.) it's a safe bet that it probably won't take a Cyrix chip. In that case, the Intel chip may be your only alternative.
Video
If you did buy that system at the local superstore (and you know who you are), chances are your system doesn't have the best video subsystem (and if it's a Packard Bell, it definitely doesn't). Not to fret, because your system should have at least one free PCI slot, where you can plug in a new video card.
As for what kind to get, the choices go on and on. If you want a card that's well supported under OS/2, the choices narrow themselves down somewhat (although not as much as they used to).
o Trident: Good OS/2 support, used in Aptivas. Drivers support dynamic resolution changes (if you can get it working). Low to Mid range cards.
o Matrox: Very good OS/2 support. Their drivers have all the bells and frills, but no dynamic resolution changing (at least, yet). High end cards.
o S3: Don't kill me, but S3 makes some good cards, and the OS/2 drivers are there. Mid to high end cards.
You should, at this point, look for a card that supports MPEG at the least. On the subject of 3D cards, I can only say that there is very little (if any) OS/2 support for 3D features. That doesn't mean that there won't be in the future, but for now I don't see any reason to shop for a 3D capable card.
CD-ROM
Quite a number of these older Pentium systems have a 2X CD-ROM. While adequate for playing music and older games, it just isn't going to be able to keep up with newer games. With prices for a generic IDE 8X CD-ROM hovering around the US$100 mark, it's a good and relatively inexpensive upgrade.
This is by no means a comprehensive list of what you could do to your system. My idea here is to keep most of the existing system intact, and just upgrade or replace small parts. While you could go out and buy a Wide/Fast SCSI card and a new hard drive to go with it, that would probably be incredibly difficult (not to mention expensive) for most users.
As always, I'm open to suggestions. Just use the mailto: link below if you have any input or other suggestions. And have a happy holiday.

***********************************
the REXX Files - by Dr. Dirk Terrell
----------
Although Perl is much more frequently used as a Common Gateway Interface (CGI) scripting language, REXX is quite capable in this capacity. Once you do the work to set up a basic template file, you can create CGI scripts very quickly. I use REXX to do a variety of CGI functions such as customer registration and online ordering for a local scuba shop.
If you are running your web server on an OS/2 machine, then REXX is readily available. However if you are running the server on a Unix machine, you'll have to make sure that a REXX interpreter (such as REXX/imc or Regina) is available. It is possible, as we will see, to write a REXX script that will run on both systems with very little effort. With my basic template, I write the CGI scripts on my OS/2 machine, and then transfer them to the Unix server when I am done. The only difference is changing the first line of the file on the Unix machine to have it invoke the REXX interpreter, an unnecessary step on an OS/2 machine, of course.
I will assume that you have a basic understanding of HTML forms, and the ACTION attribute for the SUBMIT button, otherwise I suspect you would have already stopped reading. To use your REXX script, just point the ACTION attribute at your REXX script using either a GET or POST method. In general, it is probably better to use POST to avoid having huge URLs that might run into environment variable limits on the host operating system.
Information is passed to a REXX script via environment variables when it is invoked. The manner in which the environment variables are accessed depends on the host system. Under OS/2 you use the VALUE() function, whereas under Unix you use the GETENV() function. Fortunately, there is a way to determine what the underlying operating system is: PARSE SOURCE. The following call:
Parse Source OperatingSystem CallType
will place a string in the variable OperatingSystem that identifies the operating system. The values will be either "OS/2" or "UNIX". It is then a simple matter to use a SELECT structure to do the operations necessary for each operating system:
Select
When OperatingSystem="OS/2" then Do
/* Perform OS/2-specific operations here */
End
When OperatingSystem="UNIX" then Do
/* Perform Unix-specific operations here */
End
Otherwise
/* Probably want some error handling code here */
End
For the remainder of this article, I will assume that our host machine is an OS/2 machine. Consult the example script to see the minor differences for Unix.
The first thing to get is the request method, either POST or GET. This information is passed in the REQUEST_METHOD environment variable. Under OS/2, we would use the VALUE() function like this:
env = "OS2ENVIRONMENT" /* Saves us some typing */
method = value("REQUEST_METHOD",,env) /* either POST or GET */
If the method used was GET, then we can get the query string (a string that contains the form information that we presumably want to process) from the QUERY_STRING environment variable with
query_string = value("QUERY_STRING",,env)
If the POST method was used, we have to do just a little bit more work. With POST, the query string is passed on the standard input stream. Reading from standard input is easy enough with CHARIN(), but how do we know how many bytes to read? The answer awaits us in an environment variable: CONTENT_LENGTH. Using VALUE() again:
len = value("CONTENT_LENGTH",,env)
Then we simply read the specified number of bytes for the query string:
query_string = charin(,,len)
Now that we have our query string, we have to decode the information. The string at this point will have the form of Tag1=Value1&Tag2=Value2..., that is, tag names and values separated by equal signs, with tag/value groups separated by ampersands. But REXX is good at parsing strings of this sort. We just parse on the separator characters. First split the query strings at the ampersands to get the tag/value groups and then split the groups at the equal signs to get the tag names and values:
i = 1
do while ((query_string \= '') & (i < 1000))
Parse var quer_string Parms.Group.i '&' rest /* Split groups */
Parse var Parms.Group.i Parms.Tag.i '=' Parms.Value.i /* tag/value parse */
After executing this code, the stem variable Parms.Tag. will contain the names of the various form elements (i.e., the entry fields, check boxes, etc.) and Parms.XVal. will hold the values of those elements (i.e., the text of the entry field, check status of the checkbox, etc.). The variable NFields holds the number of form elements that were found.
In the above code we call a function DecodeKeyVal() to convert hex codes into characters. With the HTTP protocol, certain characters are transmitted in hex, so we have to convert them back when they are received. The REXX function X2C() (hex to character) does this very nicely. The hex values are separated by percent signs, making for easy parsing. One other thing to note is that spaces are passed as plus signs, and the REXX TRANSLATE() function can be used to convert the plus signs back into spaces. Here is the DecodeKeyVal() function from the example program:
Now that you have the element names and values, you can do whatever processing is necessary for your application. Once you are done, you have to send information back to the person that submitted the form via the standard output stream (using SAY). The HTTP protocol requires that you send a line with "Content-type: text/html" followed by a blank line, and then your HTML document. If you don't get these first two lines right, the web browser will most likely report a server error.
The full example program below simply returns the form's element names and the associated values. It is quite useful for testing forms as you build them. Use it as a template for creating more complicated scripts and you'll find that creating CGI scripts becomes quite painless.

Hi and welcome to the next lesson on PM programming. In this column simple Presentation Manager programming problems and philosophies will be discussed. This Column is aimed at people who are interested in PM programming or are simply curious what makes PM programs tick. To understand this column a little programming experience (preferably in
C++) is recommended.
Last month we looked at some messages that play an important role in window creation, the WM_CREATE and WM_SIZE messages. In this issue we will focus on something completely different. Since we're still in the process of creating a basic application, we will once again focus on the frame window.
In this issue we will discuss a way to add some basic controls like a menu to the frame window. The basic program we were working on last month will be used as starting point for these new explorations.
Be lazy!
This is actually one of the key principles I use in programming. It can also be interpreted as: "Don't do what can be done for you!". The people at IBM spent lots of time developing this OS and put a lot of thought in it. Why do it over?
If you're wondering what I'm talking about, let me give a simple example. Last month we did a small program that set up one button in a frame window. We did this by simply creating an instance of the button class. The only thing we did ourselves was dictate (or calculate) the size of the button. We could have gone the difficult way and drawn the complete button ourselves; this way we would end up in a mess of graphic functions. The button class that is defined in OS/2 does all that for us.
Besides being lazy, I'm also a fan of the KISS principle (Keep It Simple Stupid). This month we will introduce resources as a possible way to keep it simple and be lazy.
Resources
Wouldn't it be great if we didn't have to program with these difficult C++ code lines, but simply draw our program on the screen and then generate it? Well, for a number of controls this is possible. We can define dialogs, and menus this way. Unfortunately, we still have to program the way the controls react to events. In future columns I will give a lot of attention to this way of programming; for now we will concentrate on menus.
But first let's describe what resources are.
In a resource file (.RC) we can describe controls with a scripting kind of language. This isn't exactly a programming language, but more a language that is used to describe the way things look. Some examples of resources that can be defined in resource files are:
o Menus
o Accelerator tables
o Dialog and window templates
o Icons
o Fonts
o Bit maps
o Strings
In most cases, we don't have to bother to write the resource scripts ourselves. With most compilers, as well as with the OS/2 Toolkit, come dedicated resource editors. These tools offer a graphic environment in which you can paint the resources you'd like to use. (See also the description of Visual Age, Borland C++ and Watcom in (http://www.haligonian.com/os2/v1n11/) issue #11).
Unfortunately, for the menu resource there usually isn't a graphical building tool. So let's see how a menu is created. The best way to illustrate this is to present an example:
MENU MAIN
BEGIN
SUBMENU "Menu ~1", IDM_MENU1
BEGIN
MENUITEM "Item 1.~1", IDM_ITEM1_1
MENUITEM "Item 1.~2", IDM_ITEM1_2
END
SUBMENU "Menu ~2", IDM_MENU2
BEGIN
MENUITEM "Item 2.~1", IDM_ITEM2_1
MENUITEM SEPARATOR
MENUITEM "Item 2.~2", IDM_ITEM2_2
MENUITEM "Item 2.~3", IDM_ITEM2_3
END
MENUITEM "~About", IDM_ABOUT
END
This is the sample for the menu we will add to the program of last month. (You can find an exact match of this script in the .RC file in this month's example). Let's try to analyze it.
If you take a look at the script, you should be able to get an impression of how the menu will look. This script describes a main menu with three entries named "Menu 1", "Menu 2" and "About". If "Menu 1" or "Menu 2" is activated it will display a submenu, the third menu, "About", is designed to trigger an event directly.
Some Definitions:
MENU: The Menu identifier is the starting point. After this keyword a whole cluster of definitions is added. Together they build the menu. This cluster must be embedded between the BEGIN and END keywords.
SUBMENU: The submenu keyword is used to declare a submenu. Everything between the BEGIN and END after this keyword defines this menu. In the submenu new submenus may be added.
MENUITEM: Defines a menu item. Just as with SUBMENU, after this keyword the name of the menu is inserted. This is the name as it will appear in the menu. Note that in some places the ~ (tilde) is used. This may be done once in a menu-name. This will result in a underline effect for the letter that is preceded with the tilde. This letter can then be used as a fast access to the menu item.
SEPARATOR: This keyword is used in "Menu 2". If a MENUITEM SEPARATOR is used, it will create a line in the menu. In our example the Item 2.1 and Item 2.2 will be separated by a line.
With the KEYWORDS described until now we can build fairly complete menus. There are however, a lot more possibilities, like buttons, etc. These will be addressed in a future column. There is another thing that I haven't explained about the above example: after almost every line there is a word (identifier) like IDM_MENU1_1. These are called resource identifiers.
Resource identifiers
The .RC file describes the resources, but the compiler (as well as the OS) must have a way to identify every resource used by a program. This is why every resource has a resource identifier. A resource identifier is a constant that is usually defined in a .h (header) file and is included in all the program parts that need to know the resource ID. The header file for Sample 3 looks like this:
#define MAIN 1
#define IDM_MENU1 100
#define IDM_ITEM1_1 101
#define IDM_ITEM1_2 102
#define IDM_MENU2 200
#define IDM_ITEM2_1 201
#define IDM_ITEM2_2 203
#define IDM_ITEM2_3 204
#define IDM_ABOUT 300
As you can see, all the menu-item identifiers have a different constant assigned to them. You're relatively free to choose these numbers. Menu items in the same menu must have different numbers. Or, if you want two menu items to trigger the same event, menu items should have the same ID.
The first file in which we include this header file is the resource file (.RC). This way the resource compiler knows which ID's to attach to the separate items. We also want to use this include file in the file in which we handle the events triggered by a menu action. To accomplish this, the following line is added to simple3.rc and simple3.cpp.
#include "simple3.h"
Why does the .cpp file need to know these ID's? Well, every time a menu item is activated, a WM_COMMAND message is sent to the client window. This means we can let the window procedure we defined for our little program intercept this message. All we have to do in the code that handles this message is determine which menu-item is pressed. (The resource identifier is used for this.) To understand how this works, let's take a look at the WM_COMMAND message.
param1 USHORT uscmd // Command value.
param2 USHORT ussource // Source type.
USHORT uspointer // Pointer-device indicator.
returns ULONG ulReserved // Reserved value, should be 0.
The only thing we need to know now is how to detect the right menu-ID. For this we only need the message parameter 1. Message parameter 2 can be used to pass information about the source that triggered the menu event. For now, we're not interested in this. (Once again, this will be addressed in a future article, so keep reading.)
You've noticed that the first message parameter is a USHORT. This means we can't simply treat it as a ULONG (which every message parameter is). We need to extract the SHORT from this ULONG. For this, there is a nice macro called SHORT1FROMMP. Take a look at the following piece of code:
case WM_COMMAND:
{
switch (SHORT1FROMMP(mpParm1))
{
case IDM_ITEM1_1:
{
// Handling menu item 1.1
}
break;
case IDM_ITEM1_2:
{
// Handling menu item 1.2
}
break;
}
}
break;
What you do in the separate menu item routines is dependant on your application. In our example, we will use the WinMessageBox API to make something happen when a menu item is clicked. (This API displays a popup box in which text can be displayed. See the sample code for this.)
Using the menu resource
At the moment we've got a resource file and we know what kind of messages the menu generates and how to handle them. If we leave it at this, we will have a window without a menu. What we need is a way to attach the defined window to the frame window. This is where the FCF flags come in (Frame Creation Flags). The Frame creation flags have been loosely mentioned in an earlier column and we will go deeper into them next month. All we've got to know for now is the FCF_flag we need to attach the menu. This can be done by adding the FCF_MENU flag.
After this is done, we need to tell the frame window upon creation which resource to load. We gave the menu the resource MAIN (1). In this code sample this is added (in previous samples this was set to 0).
WinCreateStdWindow (HWND_DESKTOP, // Parent
WS_VISIBLE, // Style (visible)
&flFrameFlags, // Creation flags
"SampleClass", // Class name
"Simple 2 for OS/2 e-Zine!",// Titlebar text
0, // Client style
NULLHANDLE, // Resource handle
MAIN, // Frame ID <======= This is it
&hwndClient); // Client handle
In future articles we'll see that all the controls that a frame window has to load that are controlled by the FCF-flags must have the same ID and the Frame ID.
WM_COMMAND and the button.
The WM_COMMAND message is sent by the menu items as they are clicked. But this command can also be invoked by other controls, most noticeably the button control. The button control will also send a WM_COMMAND to its parent when it is clicked. So, if we know the ID of the button, we should be able to intercept a button click in the handling of WM_COMMAND. (Make sure that the ID doesn't double one of the menu ID's).
Compiling .RC files
RC files must be compiled just as C++ files. To do this, we can use the RC compiler that comes with OS/2. With this compiler a .RC script file can be compiled to a .RES file which can be linked to an EXE file (also by RC). Most compiler packages though can handle resource files from within the IDE. This means we don't have to bother about doing command-line stuff. (In the Borland C++ compiler you simply include the .RC file in the project and everything will be handled.)
Concluding Notes
There is a lot that can be done with resources. What we've gone through now is only scratching the surface of what's possible. This means we will see a lot more of resources in future columns. For some applications it's an ideal way to create a program with very little
programming effort. (The Smalled HTML Extensions are an example of this; everything you see in that application is done with resources, there isn't a control that is hard coded in there.)
All changes that are new in the (http://www.haligonian.com/os2/v1n14/simple3.zip) SIMPLE3.CPP (ZIP, 16.7k) program are marked with NEW to make it easier to figure out.

For me, to work is to listen to music. Words just don't want to come out of my fingers unless I have a pair of headphones warming my ears and pumping rich tunes into my brain.
OS/2 has a broad range of CD player applets that'll suit any desk jockey with a stockpile of the shiny discs to play. Most try to mimic the front panels of traditional CD players that come with stereo systems you buy in stores. In this review I've rated each player on a 1-10 (1 worst, 10 best) point scale.
Warp's Own Compact Disc Player
The bundled CD player that comes with Warp 4 is excellent to begin with. It's not short on features and even comes with a cool "brushed aluminum" texture finish. The problem with this texture is that it can take a while for the player to repaint itself when restored from a minimized state.
Nearly all the on-screen elements of the player can be switched off individually to conserve screen space. Switching off the menu bar will place a small icon in the title bar that gives you a drop-down menu with all the same choices. I found that you could literally reduce the player down to nothing but a title bar, or just a title bar with controls, or whatever configuration pleases you. Another point I liked was that the player would identify the name of each track in the information bar as your mouse hovered over the numbered buttons.
Warp's CD player can be programmed with CD and track titles for all your favorite discs, always identifying which CD you've inserted by the unique UPC code on the disc itself. It can also be set to automatically play a disc when inserted or when the CD player is opened with a disc already in the drive. Plus, the CD player can be set to resume a CD from where it left off, the next time the player is started.
Rating: 9
Creative Labs CD Player
Packaged with a suite that also includes a .wav, .midi, movie and other utility programs, Creative Lab's CD Player is a direct port of the Windows version that comes standard with most Sound Blaster sound card and CD-ROM drive bundles. Cosmetically it's one of the best looking in this review, and surprise, surprise, it doesn't need a Creative Labs brand CD-ROM drive to work. Although I have a Sound Blaster audio card I tested this player after I had chucked the old Creative Labs 4X CD-ROM and replaced it with an 8X Mitsumi drive. It still worked flawlessly.
While not very configurable, you can still add your album info and enter a program for playing favorite tracks. The display is touch sensitive too, with controls for changing the volume, playback behavior, or to toggle between the three views; graphical view (an animated mock of your CD-ROM's front panel, showing if a disc is inserted or not), CD and track title view, and track time view.

CD in a Box 1.66
CD in a Box looks, walks and talks like an extension of the Workplace Shell folder class, but it isn't. A CD can be opened in any of the familiar folder views (icon, details, plus name and text view) with icons for each track on the disc. Right clicking on any track icon or on a blank space of the folder brings up a context sensitive menu with which you can configure the CD or track properties, mark favorite or not-so-favorite songs and more.
I found this to be the easiest and most intuitive way of entering a custom program for playing CDs. You name each track using the standard Alt-click on the icons, but you can also right click on each track icon and pick "favorite", "ordinary", or "horrible" status as your choice for that particular song. Then when you play the CD you can tell CD in a Box which kind you want to play; favorite, ordinary, ordinary and favorite, horrible, all, or selected. Pretty darn point-n-click easy, making CD in a Box one of the best in this review.
As I mentioned, CD in a Box appears at first to be a WPS class, but it's just an .EXE and doesn't need to register any classes. Besides its folder-metaphor it also comes with a more "CD-player looking" control panel, complete with the play/fast-forward/rewind buttons we're accustomed to. The control panel can be displayed in 3 different sizes (small, medium and large), depending on how much Desktop space you have and what features you need immediately available. Once the control panel is open you can close the folder view without closing the whole player.
CD in a Box is extensively configurable. Not only can you display the disc contents with any of six folder views but you can change the icons used to represent each type of track, or even change the specific phrases it uses to describe "favorite" and "horrible" tracks and whether it's "playing" or "paused" or "stopped" or whatever (perhaps this can be used for simple multilingual support?). Plus, with configurable auto-play and auto-eject features, you can minimize the player completely and just play disc after disc after disc... or just leave it in repeat mode to keep playing your favorite tracks over and over and over and over...

CD Audio
CD Audio's unique feature is that it doesn't require MMPM to be installed in order to play audio CDs, it talks directly to the CD-ROM driver. CD Audio will also not stop playback if you close the program while a disc is still playing (one wonders if that's a feature or a bug, even though it's documented). CD Audio also seems to have a problem detecting new discs inserted after the program has been launched, recognizing them only if the disc was already in the drive when you started the program.
The interface is compact but pretty simplistic. With the disc stopped you can enter a program by dialing the track numbers on the keypad and hitting the "Memory" button after each track. You can click on the Recall button to show a list of all the tracks entered into memory. CD Audio does not currently allow you to enter the titles of your CDs or their tracks (robbing me of another chance to impress you with my taste in music) but the author has planned it for future versions.

PlayBoy 1.2
PlayBoy has a very plain and simple interface, the main panel has only six buttons in all and takes up barely a couple inches of screen space. You can enter album information through a dialog that annoyingly only uses icons for its buttons and no text. Most of their purposes seem obvious, but some of them aren't. There are some potentially teeth-grinding bugs in it too; after entering the tracks of my album I curiously clicked on the button with the icon of the paper on fire, sure enough it came up with a dialog asking if I really wanted to delete the album. I clicked "No". It deleted it anyway.
PlayBoy does have an auto-play as well as an auto-eject feature, making it simple to keep the window minimized at all times and just feed discs in and out without having to restore it each and every time you change a disc. Other than that, PlayBoy's quirks and bugs, coupled with its relative lack of features, don't make it a worthwhile choice compared to the others.

DB CD Player 0.21
This freeware CD player hasn't got the prettiest interface in the world, but it does allow you to enter all your album titles and tracks and gives you plenty of keyboard shortcuts so you don't always have to use the mouse like the other players demand.
DB CD Player doesn't offer any online help. The author seems to think that the program is self-explanatory enough and I tend to agree. To configure the program you click on a button marked "Setup" and to enter album titles you click on a button marked "Titles". The rest of the player's controls are the standard VCR/Tape-deck/CD-Player buttons we're all familiar with by now. The slider bar shows what track the player is on at any given moment, but unlike the Warp CD player it does not show where in the track is currently being played. The program also features its own "one-click-zapper" in the title bar. Handy, but a bit redundant now thanks to Warp 4, Object Desktop, X it and other utilities that do the same thing.

Compact Disc Explorer 2.4
This one is a more complex CD player that has most of its configuration switches located on the main window itself, which unfortunately looks a bit messy due to the bitmaps and lines not being positioned correctly on the screen resolution I was using at the time (800x600).
CD Explorer has features that most people won't have use for, but may prove valuable for other purposes such as study or teaching. For example when the disc is stopped you can enter the cue position in the song, with up-to-the-second accuracy, and CD Explorer will start playing at that exact spot when you click the Play button again. Second is the segment repeat feature; mark the beginning of the segment, then the end (within the same song) and when you click on the repeat button it'll play that segment of music over and over until you stop it. One guesses that this might be useful for studying a guitar riff, drum solo, or maybe figuring out what the heck the lyrics are in a Michael Jackson song.
One last feature of note, which can actually be found in Warp's own CD player too, is the output through audio-card switch. If your CD-ROM drive supports DA streaming data you can direct the sound through the drive's IDE/SCSI interface and into the sound card as digital information rather than across the jumper-cable -- which only carries the analog music signal. It is not always advisable to use this; for one reason, most sound cards can't handle the huge flow of data without sounding crackly.
I do recommend that you check out the program information dialog though and see the author's sense of humor at work.

Albatros CD Player 2.0 (beta)
While this is still in Beta I decided to look at it anyway. Albatros CD Player visibly tries to mimic the cosmetics of Creative Lab's CD player with its curved buttons and LED style display. At my 800x600 resolution the bitmaps for the buttons weren't very easy to read though and I had to click-n-guess to figure out most of the interface. When you eject a disc, the black display rectangle turns into a mock picture of your CD-ROM drive's front panel, similar to the one in the Creative Labs player.
But this player also has features for recording your CD tracks directly to .wav files (if your drive supports DA streaming), and unlike the Creative Labs player, it has more features with a greater depth of configurability.
Rating: 8
Summary
Unlike the MOD players covered elsewhere in this issue, each of these CD players will reproduce your songs exactly the same way. Plus, it doesn't take an awful lot of CPU power to tell a CD-ROM drive to skip to the next track. Therefore user interface was of primary importance here.
After reviewing all these players I have come away with one wish: That they'd all use a universal database format for storing CD titles and track info. When making a decision you're undoubtedly going to try more than one player; it would be useful if you could carry the title database over from one player to another as you go. With this feature would come the possibility of running a web-based album repository, saving us all the chore of entering our huge and ever growing CD collections.

Mod Players for OS/2 - by Chris Wenham
----------
A .MOD file is a digital music file that contains a score plus digitized samples of instruments, unlike MIDI files which only contain the score and rely on your soundcard's FM chip or your synthesizer's sound bank to supply the instruments. It's also different from a .WAV file, which is just a single digitized sound or instrument. A MOD player uses a simple form of Wavetable synthesis, adjusting the pitch of each digitized sample to produce the different notes as they are called by the score. All of this digital mixing takes place on your computer's CPU and not on the sound card itself (except for the Gravis UltraSound (GUS), which has a special chip to take the load of the main CPU) meaning that your computer will feel slower during playback of a song -- after all it's trying to pump upwards of 44k per second of data to the sound card.
Also different from .WAV files is the size of .MOD files. A 30 minute song could easily be under 300K since most of the file's bulk is used to store the digitized instruments.
Also unlike MIDI files, MODule files don't always sound the same on different players. Given the wide range of file formats, each one with different features and effects, you may find that while one player can render a song perfectly another may stumble over an effect or technique it wasn't programmed to handle properly.
To complicate matters further, some players are much more bullish on CPU usage than others. The introduction of DART -- Direct Audio Real Time -- in Warp 4.0 (the .dll libraries necessary are also available for Warp 3) means that players can send data to the sound card directly, rather than going through OS/2's MMPM, resulting in much smoother, uninterrupted playback with lower CPU load.
As a test I found a MODule song called "Astronaut's Requiem" by U4ia which has a tendency to loop forever around the 18-19th track position on most players. Probably resulting from the musician using a technique that worked fine on his Tracker (the program that composes the files) but not so well on players.
A little history...
MODs came from the Commodore Amiga, that amazing computer from the mid 80's that practically invented Multimedia and showed the world what tight code and clean engineering could do. The Amiga's still around with a cult following that keeps it alive (sound like anyone you know, you OS/2-ers out there?) not to mention a cozy niche in TV production and broadcasting. (Watch Babylon 5 and catch a load of those computer generated space scenes, that's Amigas at work there.)
The MODs themselves are generated with programs such as SoundTracker, NoiseTracker, ProTracker, ScreamTracker and others. There are actually many formats too, including the original 4-channel SoundTracker .MODs, ScreamTracker's 16-channel .S3M, and FastTracker's .XM format with its 32 channels and other unique features such as envelopes and an instrument/sample model.
This ability for people to cheaply and easily compose music, then distribute it for free over the Internet has created a whole new culture some would say. Looking through the messages hidden in the instrument lists you start to pick up the names of prolific composers, working under aliases like "Deathjester", "Feekzoid" and the almost godly "U4ia" (pronounced, of course, "euphoria"). Some advertise their skills for writing video game scores, some are members of "Demo" groups, while others work alone cranking out tune after tune after tune.
OS/2 Players
For this review I've given each player a 1-10 score (1 worst, 10 best) on three criteria: Play Quality -- how well it reproduces songs and handles their 'quirks'; User Interface -- how easy it is to use and control; and CPU Load -- how efficiently it makes use of your computer's processor (and thus how friendly it is in a multitasking environment).
UltiMOD v1.5
UltiMOD comes in two versions, the character-mode and the PM version. Both have the same mixing engine behind them (and hence the same sound quality) but the character-mode version has more features and a richer display. UltiMOD uses MMPM or DART for sound output, but there is a separate Gravis UltraSound version available too.
UltiMOD's character mode interface is probably the most interesting to watch with a real-time display of the instruments as they are used, what note they were just played at and what effect they were played with. It's not as entertaining as the graphic LED displays of some of the popular DOS players but it sure as heck beats the static displays of the others in this review.
UltiMOD failed the "Astronaut's Requiem" test, sticking on the trouble spot, although we were able to 'bump the needle' by fast forwarding a track.
Supported file formats: MOD, MTM, FT1, S3M, XM
Ratings:
Play Quality: 8
User Interface: 7
CPU Load: PM Front-end: 9 Text mode: 8
DMP (Dual Module Player)
Julien Pierre's port of Otto Chrons' Dual Module Player 4.0 (a DOS program) is probably the best of the bunch in sound-quality and CPU usage. If it wasn't for its annoying lack of support for FastTracker II's .XM format this would be my favorite. It too has both a character-mode and PM front end similar to UltiMOD's, but the character-mode version offers no instrument feedback at all. It makes up for this with what I consider to be a fantastically cool range of 'filters'; mathematical transforms that affect the sound output. There are simple noise reduction filters to begin with, but you can easily flip on the "Hall reverb", "Air duct reverb", "Distant echo" or "Bass boost" to get something totally different. Many tunes take on a whole new meaning with these filters, making DMP definitely worth trying out just for this trick alone.
One interesting and unique variation of DMP is the Netscape for OS/2 plug-in. It's the same mixing engine used in DMP but this time packaged as a plug-in for the Netscape Navigator for OS/2, giving you the ability to embed any supported MODule file in your web pages for background music. Anyone with the plug-in installed will hear the music being automatically played after the page has finished loading. The music keeps playing even if you jump to another page, stopping only when the music is finished or you hit another page with a MODule embedded too.
If you want to hear this in action, (http://www.polsci.wvu.edu/Madbrain/npdsmi.html) download and install the plug-in, then restart Netscape and reload this review page. Of course, if you have already installed the plug-in, you are already hearing the music...
DMP passed the "Astronaut's Requiem" test with flying colors.
Pop Play has, without argument, the best PM interface of the lot. It's written in Visual Rexx, but has DART and wide support for module formats, behaving well with options to change the priority at which the player runs. While I found that Pop Play's sound quality was excellent, and often better than the other players, there were two files that it failed on. "Astronaut's Requiem" got caught in an infinite loop while another song called "Wedding in the Leaves" had an annoying vibration to it.
Pop Play's CPU usage varies with the settings you give it and the module it's playing. .XM files with many channels used can peg the CPU meter when played at high quality (44khz, 16-bit stereo) on Pop Play. However if you turn off screen updates, lower the priority to idle and play the module back at 22khz, 16-bit stereo, the CPU drain becomes modest and comparable to the other players in this review.
Its major strength is, of course, the interface. It has a powerful browser built into it which will display the filename of a song plus the song's title and format. You can add songs to the playlist this way, either to the top or bottom of the queue, or play them immediately. It doesn't offer an instrument listing, but you can adjust the order of the songs in the playlist on the fly and save the list to disk for later. The controls and display have a cool digital CD player feel to them with bright neon lettering on a black background.
REXX programmers may be interested to know that Pop Play also comes with a loadable DLL from which you can access and play MOD files in your own programs.
CPU Load: 7-8 (depending on features switched on during playback)
Sounder 1.2.1
Sounder is the only player in this review that doesn't use DART for its audio output, streaming it through MMPM instead. This results in a much heavier CPU load. It is also in want of an update, with incomplete features and format support.
Unfortunately, on too many modules I found the sound quality to be unacceptable. This is a shame since the user interface looks promising, showing in real-time how many channels are in use and with a window that promises to have a graphic display (like the LED graphic equalizers on some stereos) in some future version that hasn't been released yet.
Supported file formats: MOD, MTM, and S3M
Ratings:
Play Quality: 5
User Interface: 7
CPU Load: 6
Albatros Media Player 2.0 (beta 3)
Norbert Heller's Albatros Media Player is the sister of the Albatros CD Player (see the review of CD players also in this issue) and as of this writing is still in beta testing. It uses the same PM interface as the CD player except with it you drag-n-drop the MOD files you wish to play onto the black rectangle area of the player's window. The interface is still a little limited for my taste and doesn't allow you to save song lists. Albatros Media Player also failed the "Astronaut's Requiem" test, but considering the program is still in beta there may be many things that change before its final release.
If the user interface isn't a big concern to you and you're looking for the best playback quality with the lowest CPU load, try either DMP or UltiMOD. If you want good playback, acceptable CPU load and a detailed and intuitive user interface that'll impress your friends, look no further than Pop Play. Whichever you chose, be sure and grab the DMP plug-in for Netscape Navigator for OS/2 too.

After installing Warp 4 I quickly discovered that two of my most-used utilities no longer worked. The IBM EWS memory-usage display utility Os20Memu, still needs updating, but the other one, WPTools, has recently been revised and is available on popular FTP archive sites.
WPTools is a collection of Workplace Shell utilities, including Desktop backup and restore (which I've never used; I'm happy with Robosave, another IBM EWS free utility) and a utility, CheckINI, which cleans superfluous entries from the OS2.INI and OS2SYS.INI files. If you have bought the commercial product, UniMaint, this article will be of little interest to you, but if you balk at having to buy an expensive piece of software in order to perform essential system management, read on.
CheckINI is a command line tool which displays its copious output in an OS/2 window, as well as logging it to a file. When run without switches it parses your INI files and tells you what it would do if given the chance. If run with the /C switch, it will edit the files interactively, asking permission for each useless entry it would like to expunge. The entries in question are mostly references to every program, file, and desktop object you've deleted since installing OS/2! As you can imagine, these do accumulate. My experience is that these useless entries in the two INI files slow the system down and make it feel sluggish.
After using Warp 4 for several weeks it seemed that my system was slower than it was just after installation, but this is hard to judge. I tried running the copy of CheckINI from WPTools v18, but it died after numerous errors. Evidently the internal format of INI files has changed with the release of Warp 4.
When I saw that Hank Kelder had released a new WPTools to the Hobbes and Walnut Creek's FTP sites, I lost no time downloading and running the new CheckINI. CheckINI worked for nearly an hour, reminding me of all the programs (many from the Warp 4 Application Sampler CD) which I had installed and deleted. The result was a substantial reduction in size of OS2.INI and OS2SYS.INI and a noticeably snappier system. I'm running OS/2 on a 486, so any improvement is welcome!
Reducing the size of OS/2's INI files reduced my boot-up time, as the files are loaded into memory when OS/2 starts, and are periodically read back into memory in order to keep up to date with file and WPS changes. I've noticed that spurious INI file entries seem to particularly affect programs with hooks into the Workplace Shell, such as Object Desktop.
If you've ever been confronted with inexplicable WPS behaviour or error messages, the problem is likely rooted in these OS2*.INI files; it stands to reason that if these files accurately mirror the real state of affairs in your system, programs which rely
on the information they contain will run more smoothly.
An alternative to using a utility such as CheckINI is to revert to a previously backed up version of a Desktop when problems occur. I try to avoid doing this, as inevitably there are new program objects and other WPS features which will be lost and have to be recreated. The virtue of CheckINI is that it is only looking for spurious data and leaves everything else alone.
(A caveat: after CheckINI has sifted through your INI files and rewritten a new, slimmer version to disk it is advisable to reboot immediately. If you don't, the changes may not "stick".)
I strongly encourage OS/2 users to try out CheckINI. I've used it regularly for about a year and a half, and never had the utility cause damage to the binary-format OS2*.INI files. I've found that running it about once every couple of weeks keeps my INI files in good shape, but I'm a software junky; if you don't make that many changes to your system it could be run much less frequently.
If you have a relatively stable Desktop; i.e., you don't add and remove objects and icons very often, this utility might not be absolutely essential. But if you try out new shareware frequently and in general your system is in a state of constant flux I think you will be surprised at what a difference running CheckINI can make. Try it and see!

YAOS v1.6 - by Ryan Dill
----------
A lot of good things can be said about OS/2, but one thing is for certain: its default command line shell, CMD.EXE, has got to be one of the most user-unfriendly tools known to mankind. I can understand this, after all one of the biggest advantages of OS/2 is the object-oriented Workplace Shell. In IBM's mind, why would anyone use the command line except as a last resort, right?
The fact is, though, a lot of us do. For those with low-memory systems, a command-line window is a fast and easy way to get things done, one which requires less drag on the system than, say, the Drives object. Many of us are at home in command prompts from using UNIX perhaps, and despite loving the power of the WPS, still use the command line for much of our 'quick-and-dirty' work.
IBM's CMD shell doesn't take full advantage of many of OS/2's features. Long filenames in HPFS, for example, can be accessed through the command line, but only by "Typing the long name fully and enclosed in quotation marks". Ick. Wouldn't it be easier if you could complete that filename without bothering with quotes and without having to type the whole thing?
Those of you reading this who know about JP Software are probably saying, "Yeah, but you can do that! Just get 4OS2!" JP Software's 4OS2 is a great product, but that's not what I'm here to talk about, because I don't need it. I use the amusingly named "Yet Another OS/2 Shell".
Despite the name, YAOS is anything but just another shell. It allows command-line completion of filenames, command aliasing, drive-wide "cd" (change directory) switching, command history, executable extensions, and more. Why should you use YAOS rather than 4OS2? Simple: it's free, and according to the author, probably always will be.
Maybe I should explain a few of these feature for those of you who aren't command line fanatics. In my opinion, YAOS' most useful feature by far is its command-line completion ability. Just type in the first few letters of the filename you want to access, or the directory you want to switch to, and press <TAB>. A little window pops up displaying the files/directories which match the first few letters you have typed, allowing you to select the one you want with the cursor keys. If you want to switch into the directory "Boy_this directory name_ is long...It has_Spaces too", just type
cd b <TAB>
and YAOS will automatically stick its name on the command line, all spaces and characters included. If there's more than one file or directory starting with the same letter, you can either select the one you want from a pop-up list, or press <ESC> to get out of the list and type a few more characters, then press <TAB> again to get a better completion.
YAOS also appends a slash '\' to the end of the name if it's a directory, so if you're trying to access a file a few directories deep, it's still a snap. If there's a file called "January's business statistics" in the above directory, just type something like
cd b <TAB> j <TAB>
and it'll complete the filename with its full path; then just hit return. Command line completion is a feature which, if you use the command line at all, is an essential time-saver, especially if you've got long filenames or those with spaces in them.
The shell also has a similar way of accessing previously-used commands; not only can you access them by using the cursor up and down keys and/or <TAB>, hitting <ALT-H> will bring up a full list of commands you've typed since the shell was started. Or, if you're used to UNIX, you can use syntax like '!4' to execute the fourth-last command, '!!' for the most recent command, etc.
YAOS allows you to use aliases, as well. Define an alias like
p=play file=%1 dev=waveaudio01
and you can play wav files from the command line just by typing 'p filename'. Save aliases to a file and give YAOS the right parameters when you start it, and those aliases are always available. Aliases are another thing which, once you've gotten used to, you'll wonder how you ever did without them.
Another cool feature is that YAOS can be set up to use file associations. Just type the filename by itself and hit return, and YAOS will run the application you've associated with that file type with the filename as a parameter. Set up something like
ext zip=d:\compression\unzip
and when you type the name of any zip file (even with path info, like d:\temp\thisfile.zip) then YAOS will run unzip on it, extracting the contents to the current directory.
YAOS has more features than you can shake a proverbial stick at, including a built-in kill command, EMACS-style editing commands, the ability to change to a directory just by typing its name (no cd needed!), the ability to start programs in separate sessions (which allows you to get back to the command line while the program is running), the ability to locate any executable in your path with a single command, the ability to quick-switch to any directory on your drive just by typing its name in, and the list goes on. Basically, anything the CMD.EXE shell can do, YAOS can do, and better. Anything 4OS2 can do, YAOS can probably do, and cheaper.
If there ever was a "must-have" app, this is it. IBM should include this program with Warp instead of CMD.EXE. Download it and try it out! You won't be sorry you did.

ColorWorks Twain Scanner Plug-In - by John Dierdorf
----------
Twain for OS/2 ColorWorks Scanner Plug-In and Consumer Driver Pack Bundle. This is the unwieldy name for a two-diskette package from Solution Technology, Inc. adding scanner capability to OS/2.
Installation
The first diskette is their Twain Scanner Driver package, which allows OS/2 access to several brands of scanners attached via a SCSI interface or otherwise. (Check (http://www.gate.net/~stidev/) STI's web page for a complete list of supported and to-be-supported scanners.) Installation is simple; the end result is a new directory called x:\STI and two new lines in your CONFIG.SYS. Any Twain-enabled application should then be able to use the scanner; examples of such are the latest version of PMView as well as STI's own Applause and Review.
The second disk in the package makes ColorWorks Twain-enabled via a plug-in module; installation is equally simple.
I purchased the bundle from (http://www.os2store.com/) J3 Computer Technologies and installed it on a brand-new (http://www.sios2.com/) Simply Intelligent Pro-200 system (preloaded with Warp 4) with my old HP IIc scanner attached to a Tekmar PCI SCSI controller. There were a couple of minor glitches in my installation -- the included READ.ME file refers to hardcopy documentation that is not, in fact, provided, and a diskette file was somehow misnamed -- but otherwise installation pretty much consisted of typing "A:INSTALL" twice. (STI responded in a matter of hours to my e-mail about the discrepancies.)
Features
I'm a semipro portrait photographer, and I've now used PMView (v0.93), ColorWorks (v2.0), and Galleria (v2.31) to scan many of my photographs. After installing the Twain driver both PMView and ColorWorks will have an "Acquire" option enabled in their FILE drop-down menu; in either program selection of that option will bring up STI's dialog box where the user can set up the type (Color Photo or Drawing, B&W or B&W halftone, 16 or 256-color grey), resolution, brightness and contrast corrections, and the dimensions of the object to be scanned. Clicking the "Scan" button causes the program to work exactly as advertised; the resulting file will be displayed, can be manipulated by PMView or ColorWorks, and then can be saved in any supported format -- TIF, GIF, BMP, JPG, etc.
My only real WIBNI ("wouldn't it be nice if...") for the STI driver is if its dialog box included the ability to preview and pre-crop an image to be scanned. It can be done, because Galleria, even though using the STI drivers, provides its own dialog box with just that capability. In the illustration, only the selected area of the preview will be scanned. This is very handy when you are only interested in a small area in the middle of an 8.5 x 11 page; with PMView or ColorWorks you're pretty well stuck with scanning the entire page into a multi-megabyte file and then cropping afterwards. (STI indicates that preview capability is under consideration for a future release.)
Performance
One other observation: Don't plan on doing much else while you're waiting for a scan to complete. The scanning software is an incredible CPU hog; even my Pentium Pro 200 slows to a crawl until a scan ends. (STI also said they're working on a multi-threaded SCSI driver for the TWAIN data source to alleviate the resource-grabbing.)
Conclusions
I'm very satisfied with the STI bundle; it does what it's supposed to do, cleanly and efficiently. If I'm just trying to scan a quick image to add to a web page, I tend to use Galleria because of the preview capability. PMView gives better color-correction options,
and of course, if image touch up or all-out manipulation is needed, the impressive bulk of ColorWorks looms comfortably in the background. (Color correction will be part of the TWAIN data sources in the future to give almost automatic and better color. For now, stable working drivers are top priority at STI.)
The bundle as described (Twain driver and ColorWorks plug-in) is available for US$79 from J3 or Indelible Blue, among others. Note that if you own STI's Applause or Review then you already have the Twain driver and only need the plug-in to add ColorWorks scanning abilities; that half costs US$49. If you don't own ColorWorks (you should!) then the Twain driver to enable PMView and Galleria also costs US$49 by itself. In all fairness and with the recent reductions in the price of ColorWorks, it seems somewhat odd that the plug-in is half the cost of ColorWorks v2.0 itself but still a fair deal.

First Looks: Corel Office for Java - by Christopher B. Wright
----------
The Corel Office for Java pre-beta (at (http://www.corel.com/) http://www.corel.com/) does run on the Netscape Navigator for OS/2 beta 2 release. I had read on the 'net that it didn't, but if you install everything correctly, it should run (albeit very slowly).
If you can patiently sit through the loading process (give yourself at least half an hour with a 28.8 modem) and don't mind waiting five minutes between mouse clicks, you get a marvellous display of Java technology in action. I'm not exaggerating about the loading times; Corel clearly warns testers before they begin loading the suite that it will take some time and that they recommend at least a full ISDN connection.
So far, I've managed to run this Java application from a machine running NT, a machine running the Mac OS, and my home computer running OS/2. Here's a rundown of interesting features:
o In all cases, the interface uses the basic GUI features of whatever OS Java is running on. In other words, NT 4.0 machines display windows with the "X" close button at the upper right hand corner of the screen, and that weird textured corner-tab thing at the lower right, along with thick Win95-ish scroll bars that resize in accordance with the amount of information not displayed in the viewable area of the window. Running on the MacOS, you get the upper-left close button, the lower-right resize area, and the MacOS scrollbars. You also get "Window Shade" features if you've set that up in your extensions folder. And in OS/2, (Warp 4 is the only version I've tried) you get the skinny 3-D scroll bars) (resizable, like NT's) the new min/max/close buttons (haven't tested it with the Object Desktop replacements, but I assume they'll work too), etc.
o The stuff inside the window is a little more generic... The buttons and menu text look very Windows 95-ish (the menu text font seems standard, it is not replaced by whatever you've chosen for your Desktop... sorry, no WarpSans). Still, the icons are nicely done and the drop lists under OS/2 act like OS/2 drop lists (you have to click on the button to activate it, whereas in Win95 and NT you could click on anything, even the name, and the list would drop down).
o Only WordPerfect, Quattro Pro and something called "Pasteboard" are active, but it looks like they intend to include a Java version of CorelDraw in the final packages (there's an icon designated for it, shaded out, on the initial chooser screen).
o The pre-beta version of WordPerfect on display is very basic, a few fonts, a few formatting commands -- not like the full-featured Word Processing apps we're used to. Still, it's enough to play around with.
o As I mentioned before, it's very slow. All us fast typists will be frustrated, as there seems to be a two second delay between typing each letter and seeing it displayed.
Despite the incredible slowness and the sparseness of features, this is really, really cool and I hope Corel can pull this off quickly. If they can, it should open up the software market -- no longer would software companies be developing for platforms, they would be developing for one big market. Then it would be up to the Operating Systems themselves to attract users by their merits, not by what they can run.
Corel is not the only company betting on this strategy as a long term bet, but they may be one of the first out of the gate.

CFSPoker v1.03 - by Sidney Maplehurst
----------
A few months ago, I reviewed the freeware game, VPoker. After having a look at that relatively simple diversion, it seemed logical for me to follow up with a look at what might be considered it's big brother -- CFSPoker.
CFSPoker picks up where VPoker leaves off in almost every way. There are more options, more games, more sounds, and, basically, more everything. A product of C F S Nevada, Inc., CFSPoker was written by former OS/2 Magazine Contributing Editor, author of the REXX Reference Summary Handbook and general REXX guru, Dick Goran.
Rough Edges
First, let me discuss the shortcomings of CFSPoker, since there aren't many of them and I can do it in just a few sentences. The few dislikes that I had with CFSPoker were mostly related to the interface. CFSPoker is a VXREXX program and accordingly is not the fastest application I have ever seen. This is not an issue with a gambling game in terms of performance, but screen redraws and setting up games caused irritating lags on the 486 machine I was using.
The graphics in CFSPoker are also not brilliant. Again, this is just a video poker game and fancy graphics aren't going to enable players to win any more, but they would have been nice, especially with the amount of detail and quality that was put into the rest of the game. If you are interested though, you can substitute your own bitmaps for card backs.
But...
Now the good stuff.
CFSPoker is the mother of all video pokers, at least when it comes to OS/2. It is not just one game, but nine different variations of video gambling rolled into one package. Some of the variations include: 7's Wild; Deuces and Joker Wild; Jacks or better - Bonus; and Kings or better - Triple Bonus. Basically, each of these games plays the same as the video poker terminals in bars everywhere; the player bets, five cards are dealt, the player can hold none, some or all of them and have the rest redealt. The resulting hand is scored based on odds decided by which type of game is being played.
Here's the twist though: CFSPoker uses an interesting idea that is a cross between shareware, regular commercial software and plain old gambling. The user downloads the software for free, complete with 1,000 credits. She is free to play until she loses all 1,000 credits (don't think you will?) after which, to continue playing, a registration key must be purchased.
The idea is brilliant but I wonder if it might backfire. Playing the game is genuinely fun because you know that if you win, you're playing for free but if you lose, you'll have to cough up to continue.
Once you purchase a registration key, the credits become unlimited. It seems to me that you lose some of the risk of playing if you know that losing won't cost you any more than the effort required to push a button. I think a better idea would have been to sell a registration key that was the equivalent of 5,000 more credits (or some number). Then, if a registered player lost all those, another, lesser fee could purchase another 5,000 credits. And if that person continued to lose so badly, a final fee (we don't want to contribute to crime or broken homes in order to support gambling habits!) could purchase unlimited credits. More money for C F S Nevada, Inc., more risk (and fun!) for the player.
Of course, this would be skirting a fine line between gambling and "real" purchasing so it may have been more of a legal decision than anything that made C F S Nevada, Inc. decide to package the game the way they did. Whatever the rationale, the credit manipulation options once the game is registered are well thought out. Players can keep track of credits won or lost between games or between sessions and can "buy" an extra 100 or 1,000 credits (which has little meaning since credits are unlimited to registered players and is supposedly possible simply to maintain consistency with "real" video poker terminals).
Sounds!
CFSPoker makes simple but good use of MMPM. Winning hands are announced (aside from being highlighted on screen) with a random .WAV file that is sure to please. These include Yabadabadoo, the Tonight Show Theme, a great Yeeeeeeeeehaaa (sniff, why it makes a girl feel like she's back in Georgia), coins dropping in a payout slot and, of course, Elvis singing "All Shook Up". Very Vegas.
Logging
The game has excellent facilities for keeping track of your winning and losing streaks. Statistics on these, including your High credits and Low credits marks, time played, hands played, hands won and lost and amounts won and lost (itemized by game type), are available from a menu or are optionally displayed when you exit the program.
Conclusions
This version of video poker takes the game to a new level for OS/2 players. Its simple and useful interface, and the great idea to give away 1,000 credits, as well as the loads of options and game variations make it a must have for any OS/2 gambler.

Fall COMDEX: Rumours from the Floor - by Doug Hicken
----------
Every year I take a few days out of my schedule and travel to Fall COMDEX to see what's new in regard to OS/2. In years past, IBM has made it a point to show off OS/2. This year, however, they took a different approach at their booth.
IBM had only one machine that they demoed Warp 4 on. Other vendors used it to demo their products, including Lotus, but IBM had only one person showing what Warp 4 could do. Instead, IBM offered "Solutions"; some of the solutions, like Voice Pilot, used OS/2, others used NT and Win95. In fact, they demoed the complete version of Voice Type Dictation on a Win95 machine. Their booth was much smaller than in years past. I was disturbed that IBM did no advertising that I could find for OS/2 at COMDEX.
While at the IBM booth, I talked to Terry Hamilton of True Spectra, makers of Photo>Graphics. Terry used to be an IBM representative for TeamOS/2 until IBM once again decided to back away from their support of that organization. Until just before COMDEX, TeamOS/2 was unable to get support from IBM to run any demos or to even get shirts for TeamOS/2 members. At the last minute, someone in Austin okayed funds for TeamOS/2 members at COMDEX. TeamOS/2 members were on the floor doing installs and made their presence known. As far as I know, support for TeamOS/2 from IBM is still up in the air.
For some time now, many insiders have felt that the OS/2 development community is very leery about their future. Most of the OS/2 vendors I talked to at COMDEX have plans to go multiplatform -- they have to. TrueSpectra, InnoVal and Stardock have all announced plans to go multiplatform, with others making plans to do the same. I also got the sense that many feel Java isn't going to be the savior of OS/2.
Speaking of Java, Corel demoed their Java suite, and it does work -- but it seems it will only have 20% of the features of the "real" suite. Why would anyone want to use a program with less functionality? Hopefully they will add the rest of the features soon, but it won't be a killer app at first. (editor's note: see our First Looks at the Corel Java Suite in this issue.)
I was surprised to hear from Corel that IBM Hursley in England has been very cooperative with them and that the suite runs faster using OS/2 (with the 1.02 Java runtime that comes with Netscape Navigator beta 2) than with any other platform. That was the best news I heard all week.
Lotus had working versions of Word Pro and Freelance Graphics that should ship before Christmas. The shipping versions will have FixPak 26 for Warp 3 and FP 1 for Warp 4 to get Open32 to work right. They were very knowledgeable about the products and said it had been a long year for them because of problems with Open32. The versions I saw were very stable compared to the betas most of us have tried.
Speaking with DevTech at the show, I found that they are frustrated with IBM regarding bugs in WarpCenter that make it "undistributable" in the corporate environment. Supposedly, the Warp 4 WarpCenter isn't object oriented and therefore can't be set up and simply transferred from one machine to another. DevTech told me they are telling their corporate clients to shut down WarpCenter to increase the stability of OS/2 and to be able to distribute Desktops. IBM knew there was a problem in April and wouldn't fix it because, "it was too late". IBM at their best.
Techies at Creative Labs mentioned that IBM was provided with beta versions of FULL DUPLEX drivers for Sound Blaster cards around April that were to be included in Merlin. Unfortunately, Creative Labs never heard back from IBM. It will be interesting to see if they continue to develop drivers for OS/2.
As many of you know, PowerQuest has just released v3.0 of Partition Magic. Because the majority of PowerQuest's sales are now in the Windows arena, most of the new features are for Windows users. And they are having a hard time justifying OS/2 development costs. They made it clear that they aren't abandoning the OS/2 market, but that most of their development effort is now geared at the Windows user.
Maybe now is a good time for all OS/2 users to start writing to PowerQuest and other OS/2 companies requesting that they continue their support of OS/2. Or even better, to continue buying their products to show them we are still committed.
In other news, there were rumours that Inside OS/2 (a German OS/2 print magazine) is considering coming to North America with their publication. It is a good looking magazine full of tips for exploiting OS/2. I got the impression that they are testing the water and like what they see. It is also rumoured that the magazine's staff has been in contact with OS/2 Magazine regarding their past operations.
Finally, though some of the news from COMDEX was bleak, IBM insisted that they will continue to release updates for OS/2 on the Web that not only fix bugs, but that add functionality until a new release in '98. And so ends my Rumours and Thoughts from the floor of Fall COMDEX '96.

How to share an Internet
connection for little or no cost - by Ethan Hall Beyer
----------
A basic guide to setting up a SOCKS server under OS/2
In these modern and connected times, a certain issue seems to become a problem more and more often. Many people in the same house or apartment own a computer, and they all want to use the Internet at the same time. The days of cheap, dedicated high speed Internet connections is yet to come, so often the only solution in these cases is to jockey the use of a single modem phone connection. So Internet users in this precarious situation need to figure out how they can all simultaneously Get On The Net. Thankfully, it's not that difficult to do if the computers are already networked in a small home LAN.
Even if the systems aren't networked, some surfers might find the initial investment required to link their computers together well worth it. In this brief tutorial I'll explore how you can set up an computer that is running OS/2 and connected to the Internet, so that other systems connected to the OS/2 machine through a private network, can also access the Internet. And as always, minimal cost for this venture is of interest as well.
The OS/2 server software that allows this "sharing" was made available a few months ago and is now quite mature (despite some bugs, which I am pursuing with the author). This software is a "SOCKS server", and the machines on the private network that need to talk to the Internet, are "SOCKS clients". In a nutshell, here's how it works:
On the clients, the TCP/IP programs know which addresses designate sites on the real Internet, and which ones indicate machines only on the private network. For requests that go to the Internet, the client machine instead sends the request to the SOCKS server which then talks to the real Internet machine, and makes sure that the response it receives is forwarded to the correct client machine. This is done for any type of command that must go to a system on the Internet.
For more technical information on SOCKS, explore the (http://www.socks.nec.com/) NEC SOCKS site. There is a lot of information here, and setup information for other non-OS/2 systems.
In summary, here are the steps needed to set up a working SOCKS network over an existing LAN:
1. Download, install and configure the SOCKS server (SOCKD.)
2. Download, install and configure the NAME SERVER for the SOCKS server (BIND, DNS Kit, or DNSPROXY.)
3. Test the SOCKS server from a client machine.
4. Configure the computers on the network to talk to the SOCKS server.
5. Automate the startup procedures for the SOCKS server.
So, to get many machines all using a single Internet connection, what do you need to do? First, the computers that will be sharing the connection must be networked together with TCP/IP. This guide isn't a tutorial in setting up a LAN, as there are excellent How-To's on this topic available on the 'net.
Assuming the private network is functioning properly, the required software can now be set up.
Setting up the Socks Server
The OS/2 machine that will be running the server requires two key software options:
1. The actual SOCKS server, properly configured.
2. A Domain Name Server (DNS). For the SOCKS server for OS/2 to function, it requires that a DNS also be running.
Setting up the actual SOCKS server is quite simple. First, obtain the distribution file and unzip it into a separate directory. Though the server can be customized extensively, only a single basic setting is required. This can be set interactively within the server itself once it's running, but I prefer to edit the text configuration files directly.
In your ETC directory, create the file SOCKD.CFG with the single line
permit aa.aa.aa.aa bb.bb.bb.bb 0.0.0.0 0.0.0.0 ge 0
where "aa.aa.aa.aa" is your private network address and "bb.bb.bb.bb" is your private network address mask (netmask). For example, see the settings I use.
This file specifies which systems can "talk" through the SOCKS server. In more complicated setups, you could restrict which machines can go to the Internet, and even to which sites on the Internet. Explore the server's help files for more information on these settings.
Once this file is saved, start the server by running SOCKD.EXE. There is no install program, so you might want to create a program object for it.
At this point there still isn't any local DNS running, so the server cannot yet be used.
Setting up the Domain Name Server (DNS)
Having a DNS on the private network is nice. It allows the computers on the network to refer to other systems by name instead of by TCP/IP address, which makes things a lot easier. That aside, the SOCKS server (called SOCKD, or Socket Daemon) for OS/2 requires one, so for our purposes, you will have to set it up.
Surprisingly, it is configuring the name server that is the most complicated part of this whole procedure. There are three main options, and I'll cover how each one is set up.
1. IBM DNS Kit for TCP/IP for OS/2
2. Berkeley Internet Name Daemon (BIND) 4.9.4 OS/2 port
3. DNSPROXY for OS/2
1. IBM DNS kit for TCP/IP for OS/2.
This is the commercial name server software available from IBM for OS/2, released a few years ago. Quite expensive. Actually, very expensive, considering the next option (#2.). It requires a complicated set of configuration files, and is difficult to set up at first. DNS Kit is a complete server, as is BIND, so features such as caching and local name definition may offset the difficult setup. But since a true server does more, running it in the background requires more system time.
Look here for a information on setting up a basic DNS Kit configuration.
2. BIND 4.9.4 for OS/2.
Berkeley Internet Name Daemon for OS/2 is an EMX port of a UNIX name server, for OS/2. Since all name servers essentially share the same origin, BIND is very much like DNS Kit -- except it's free. Otherwise, BIND and DNS Kit can share the same configuration files, though BIND requires that these files have names only possible on HPFS drives (due to its true UNIX origins; if anyone does have BIND running on a FAT system, please let me know). Also, BIND seems to require more overhead than does DNS Kit. But still, to choose between DNS Kit and BIND, I recommend the latter, for cost reasons only.
Look here for a information on setting up a basic BIND for OS/2 configuration.
3. DNSPROXY for OS/2.
This is part of a commercial suite of proxy servers for OS/2, though DNSPROXY may be available separately. It is a very low overhead DNS server by proxy, and requires no setup. It only forwards requests, and is not designed to add local host definitions. As such, all local name resolution for machines on the private network, must be done via a HOSTS file. Contact the author to purchase this product, at (http://www2.dhinternet.com/sophisto/) http://www2.dhInternet.com/sophisto/.
When the DNS is up and running, you should be able to start of the SOCKS server. First, connect to the Internet with OS/2 machine running the server. Then, start up the name server and, finally, update the your configuration "RESOLV" files so that you actually use the local DNS instead of the one appointed by the ISP. Obviously, this tedious procedure should be automated, and I will discuss this at the end of the article.
To test that the server is functioning correctly without further work (you don't need to test this but, if there are problems, it might save some troubleshooting,) you can use WebExplorer or Netscape on one of the machines on the private network to test the server. Configure the browser to Enable a SOCKS server, and enter the IP number of the OS/2 system running the SOCKS server you just set up. If all is well, and the server is connected to the Internet, you should be able to access and view Internet pages from the machine on the private network.
Setting up the Socks Clients
Once the SOCKS server is set up, all the machines on the private network that need the ability to talk to the Internet, must be configured to use the server. One of the nice things about TCP/IP and its standards, is that any operating system adhering to those standards can talk to all TCP/IP servers, regardless of what hardware or software those servers are running. So in this case, in which the server happens to be running OS/2, there is no limitation on what the client system is running, as long as that client machine can be "SOCKSified", or configured to use a SOCKS server.
There are four key bits of information needed to SOCKSify any system. Though the actual configuration terms used may vary from system to system, what each system refers to should be clear.
1. SOCKS Domain: This it the domain name chosen for the private network.
2. SOCKS Name Server: Since the OS/2 machine running SOCKD is also running a DNS, this is the numeric IP/machine number of the OS/2 server running the SOCKS program and dialed out to the Internet.
pr3. SOCKS Server: This is identical to the SOCKS Name Server (remember, both DNS and SOCKD are operating together on the OS/2 machine.)
4. Direct Routes: This is a list of network addresses and netmasks that are accessible on the private network, and don't need to be directed to the SOCKS server. In a simple private LAN, this is the private network address and netmask.
OS/2-based client systems.
The primary focus is here, since this is what most people are running (I hope). The newest version of OS/2, Warp 4, comes with SOCKS server support built directly into the system, and it need only be enabled by entering the appropriate configuration information. Under Warp Connect, SOCKS support must be downloaded and installed separately, then configured.
NOTE: Make sure you do NOT enable "SOCKS support" in the TCPCFG configuration notebook on the OS/2 machine running the server, unless you know specifically that server machine must communicate through a DIFFERENT socks server, to talk to the Internet. If this is the case, enter the configuration information for that other server, and not circular references to the SOCKS server it is running itself.
Warp 4
Under Warp 4, all SOCKS client configuration can be done via the TCPCFG network configuration notebook. Open it, and switch to the "Socks" tab. Here are the values you should enter:
Page 1/3
[X] Enable SOCKS
SOCKS Userid: (leave blank)
SOCKS Domain: (Enter the SOCKS domain name as determined above.)
SOCKS Nameserver: (Enter the SOCKS name server as determined above.)
Page 2/3
Configure DIRECT Routes.
Choose "Add", with these values:
Destination IP Address: (Direct route IP as determined above.)
MASK: (Direct route mask as determined above)
and put in the Destination IP Address and Mask for the direct routes
as indicated above. For simple networks there should only be one
entry.
Page 3/3
Configure Default SOCKS Servers
Choose "Add", with these values:
SOCKS Server: (The SOCKS Server as determined above.)
Destination IP Address: 0.0.0.0
Mask: 0.0.0.0
Alternatively (and this is how I prefer doing it), the text SOCKS setup files can be edited or created directly by hand. In the client machine's ETC directory, there are two of these configuration files. Enter the values indicated, without parentheses (see the sample configuration files for an example.)
File SOCKS.ENV:
SOCKS_FLAG on
SOCKS_DOMAIN (SOCKS Domain)
SOCKS_NS (SOCKS Name server)
SOCKS_SERVER
SOCKS_USER
File SOCKS.CFG:
direct (private network address) (private network mask)
sockd @=(SOCKS server) 0.0.0.0 0.0.0.0
Warp 3
To SOCKSify a Warp 3 box, first download the "beta" SOCKS code for Warp Connect. Download it to the \TCPIP directory, uncompress it using the "unzip" utility, and then run UPDINST from within that directory. As with the latest version of Warp, the configuration can then be done from the TCPCFG configuration notebook, but for Warp 3 this is the only option, as the information isn't stored in text-files.
Automating it all
By now, all the basic ingredients to getting a working SOCKS server sharing an Internet connection, are in place. However, to make the system smooth and worry-free, everything should be automated.
The SOCKS server determines how it forwards requests to the Internet by looking at what TCP/IP connections are active when it starts. Unless you're one of the lucky ones who has a fixed dialup IP number, the server should be restarted after each connection so the new connection values are used. SOCKS can be configured to start the connection automatically when a request for an Internet site is received but, in my experience, there are some slight glitches when this is enabled. (I'm pursuing these with the SOCKD author.)
In addition, connections to the Internet usually imply that whatever Internet dialer is used, updates the server machine configuration files to point to the DNS server operated by the Internet provider. But the SOCKS server is running its own DNS, and should make use of it. So, as well as restarting the SOCKS server after each connection, the DNS configuration files on the SOCKS server must be reset to "point" to the DNS it is running itself. These files are the RESOLV and RESOLV2 files in the ETC directory. They should be identical, and of the form
domain (domain name)
nameserver (server IP address)
The "server IP address" can also be the loopback address, if the loopback (127.0.0.1, usually) is defined on the server. Consult the online TCP/IP help for information on this.
In order to automate these tasks, they should be run immediately after a successful connection is established. Some dialers (such as In-Joy or the IBM Advantis dialer) or dial scripts (such as PPPDial) allow you to specify commands to be executed upon connection. If one of these programs is used, it can be configured to perform the required tasks by calling a CMD batch file that performs the required operations. If this CMD file cannot be run automatically, it can be placed in a program object and started manually when needed, after connection. Refer to dialer documentation for information on setting up the "autostart" options.
A sample "autostart" script (STARTSOK.CMD) is provided, though different ones can certainly be used.
Warm Socks
Once everything is set up properly, a SOCKSified private network is a joy to use, and well worth the time it takes to set it up initially. However, this type of setup is not ideal for all situations. There are alternative methods to sharing dialup connections, such as IP Masquerading, and serving by proxy. I haven't experimented with either.
There are also limitations to the SOCKS technology that prevent specific Internet applications from functioning. Notable examples are the PING command, and DCC transfers in IRC programs (though otherwise IRC works fine through a SOCKS server). Finally, this whole guide assumes a true LAN, and not one based on direct serial connections. Expanding this setup to include machines directly connected to the SOCKS server via serial cable (much cheaper than Ethernet or Token Ring) may be a topic in an upcoming issue.
By now, hopefully everything is set up and working properly. Feel free to (eahallbe@ibm.net) e-mail me if there are questions, and I will answer as time permits. Many thanks to David Head for providing a "test case" in addition to my own private network.

Files That You Need to set up a functional SOCKS server
----------
BIND PORT:
The free OS/2 EMX port of (ftp://hobbes.nmsu.edu/os2/unix/bind494pl1_exe_a.zip) Berkeley Internet Name Daemon. Almost a drop-in replacement for IBM DNS Kit, but requires HPFS, and uses slightly more overhead.
DNSPROXY:
Small (http://www2.dhinternet.com/sophisto/) proxy domain nameserver that redirects all requests for Internet names to a real DNS on the Internet. Commercial.
EMX LIBRARIES:
These are (ftp://hobbes.nmsu.edu/os2/unix/emx09c/emxrt.zip) extra files (ZIP, 537k) required for running some UNIX ports such as BIND for OS/2. Install according to instructions in the file.
GO 1.5 PROCESS UTILITY:
A nifty (ftp://hobbes.nmsu.edu/os2/textutil/go_15.zip) command line process (ZIP, 30k) and system utility, allows you to kill processes by executable name from the command line. Useful for starting and stopping the servers from the command line.
IBM DNS KIT FOR TCPIP FOR OS2:
Commercial product available from IBM Direct, or other OS/2 sources. Part number is 76G8086 (DOMAIN NAME SERV KIT.)
INJOY PPP DIALER:
Another OS/2 (ftp://hobbes.nmsu.edu/os2/comm/in-joy09.zip) PPP dialer (ZIP, 416k) that supports auto-starting programs. Useful if you don't use the Advantis dialer. Shareware.
PPPDIAL:
(ftp://hobbes.nmsu.edu/os2/network/tcpip/ppdial29.zip) PPP Dial script (ZIP, 36k) that allows you to run programs after connection. Useful if you don't use the Advantis dialer.
SAMPLE CONFIGURATION:
An (http://www.haligonian.com/os2/v1n14/sampcfg.zip) archive (ZIP, 5.8k) containing all the configuration files needed for my server system, and configuring a Warp 4 client system. See the README.TXT in the ZIP file to see what each file is used for, and where it should be placed.
SOCKS SERVER:
This is the actual (ftp://hobbes.nmsu.edu/os2/network/tcpip/sockd.zip) SOCKS server code (ZIP, 186k), written by an IBMer and made available free of charge.
WARP 3 BETA SOCKS CLIENT SUPPORT:
This is the "beta" (ftp://hobbes.nmsu.edu/os2/network/tcpip/socks01.zip) SOCKS client (ZIP, 697k) support for Warp Connect. This beta was finalized for Warp 4, but I don't think anything except the beta is available for Warp 3. Regardless, it works well.
Things You Need to Know to get your SOCKS server up and running
----------
If you already have a TCP/IP network running, you can skip over the domain-related information here. If not, this just suggests the basic information you need, and if there are additional issues you should consult online how-to documentation.
DOMAIN NAME:
To make things easier, you should choose a "domain name" for the private network that will be communicating through the SOCKS server. This can be anything you want, but shouldn't be a domain that is already defined in the "real" Internet, such as ibm.com. For example, I chose "clt.net" but more interesting names are certainly possible. This is the name you want for your network, not the domain name of the Internet service provider you are connecting to. Since it's private, this name won't be recognized or accessible from the Internet.
Each machine in the private network requires a unique number identifying it specifically. A network address must be used to assign these numbers in an orderly fashion. These are normal IP addresses, but they won't be visible to the "real" Internet (since it's a private network). The "10.0.0.0" address is reserved for private networks, so that you can safely choose numbers that aren't actually in use out there.
For a small private network, this means that the machines should be numbered as:
10.0.0.1, 10.0.0.2, .. , 10.0.0.40
or in a similar orderly fashion. For example, I chose to number the machines in my private network
so my "domain address" is 10.10.10.0 -- i.e. I keep the "10.10.10." part always the same, and change only the last number.
DOMAIN NETMASK:
Just use a netmask of "255.255.255.0" unless you know specifically that need something different. Make sure that all the computers on the private network have IP numbers that are different only in the last number (i.e. 100,110,120 and 130, in my case).
MACHINE NAMES:
For each machine number, choose a specific name associated to that number only. Using names to refer to computers is easier than remembering the unique numbers.
For example, for my network, I have
10.10.10.100 hobb
10.10.10.110 slug
10.10.10.120 deimos
10.10.10.130 max
These are combined with the domain name to give each machine a full name, such as "deimos.clt.net" for 10.10.10.120 on my network.
SOCKS SERVER ADDRESS:
The unique IP number assigned to the machine on the private network that will be running the SOCKS server and domain name server. In my case, this is 10.10.10.100.
SOCKS SERVER NAME:
The name associated to the SOCKS server address. In my case, this is "hobb" (hobb.clt.net is 10.10.10.100.)
SERVICE PROVIDER DNS IP:
The Internet IP number of the machine on your Internet service provider, that runs a real domain nameserver (DNS.) This is the machine that your private name server will talk to get "real" Internet names. In my case, I use "165.87.201.244", one of the name servers operated by IBM Advantis, my Internet service provider.
SERVICE PROVIDER DNS NAME:
The Internet name associated with the DNS IP, if any. For example, my DNS server 165.87.201.244 is called "ns01.ny.us.ibm.net". Many providers don't allocate names to their nameservers. If this is the case, simply use the DNS IP number as its name (i.e. dns ip number: 199.166.254.4, dns ip name: 199.166.254.4.).
ETC DIRECTORY:
The configuration for TCP/IP and other networking functions are stored in an "etc" directory, on OS/2 and on other systems. To figure out where this directory is located, type
ECHO %ETC%
from a command prompt under OS/2. Usually, it's X:\MPTN\ETC or X:\TCPIP\ETC, but could be something else. This will be needed for both the client and the SOCKS server machines.

***********************************
Here is a description of all the files required for my sample configuration:
NAMED.BOOT - Domain nameserver boot description file. Should be
placed in the ETC\NAMEDB directory, which will need to
be created. Required for BIND.
NAMED.BT - Identical to NAMED.BOOT, but used by DNS Kit for TCP/IP
on FAT systems. Must be placed in ETC\NAMEDB.
NAMED.CA - Domain nameserver caching server definition file. Must
be placed in ETC\NAMEDB. Used by both DNS Kit and BIND.
NAMED.DOM - Domain nameserver domain name definition file. Must be
placed in ETC\NAMEDB. Used by both DNS Kit and BIND.
SOCKD.CFG - Permissions file for SOCKS server. Must be placed in ETC
directory. Used by SOCKD.
SOCKS.CFG - Warp 4 SOCKS client configuration file. Must be placed
in ETC directory. Used by the TCP/IP in Warp 4 on client
machines, to talk to the SOCKS server.
SOCKS.ENV - Warp 4 SOCKS client environment file. Must be placed in
ETC directory. Used by the TCP/IP in Warp 4 on client
machines, to talk to the SOCKS server.
RESOLV.LO - TCP/IP name server definition file for the SOCKS server.
This indicates where the server should request TCP/IP
domain names it receives from SOCKS clients. Must be
placed in ETC directory.
STARTSOK.CMD - REXX script that is run to "start" the SOCKS server.
Must be edited to reflect the local setup, but can be
placed anywhere. This script should be called by your
dialer after an internet connection is established.
HOSTS - This file is a HOSTS definition file that should be used
when no DNS server is in use to resolve names for the
private domain, such as when DNSPROXY is used instead of
DNS Kit or BIND. This file should be placed in the ETC
directory on all client machines and on the SOCKS server
machine.

A Retail Experience: Minzloff Data - by Chris Williams
----------
In my travels to Europe, I've seen that people face the same concerns and situations as I am familiar with at home in the United States. The competition between PC operating systems, and the attitudes of people around them, appears to be no exception. In Switzerland, while one could convincingly argue that Windows isn't everywhere, Windows advertising certainly is. Every store that has even the most remote relationship to desktop computing is overrun by the Microsoft marketing machine.
Every store except one.
In downtown Basel, just a short walk up a steep, narrow side street from the historic Barfusserplatz, is an OS/2 oasis in a land that often seems to have gone "Microsoft Mad". If you're not careful, you'll walk right past the store window and the walnut color door that bears the name Minzloff Data. This is a computing store that deals only with OS/2 and OS/2 applications. If you're looking for DOS or Windows stuff, go thrashing around the hundreds of other stores. Minzloff Data is the only exclusive OS/2 store in Basel -- quite probably the only one in all of Switzerland! And business is good, according to Oliver Minzloff, the business founder, owner, CEO, president, and all-around head guy.
It's a truly amazing sight. A retail store with shelves chock-full of nothing but OS/2 applications. All of the ones I know and love were there, as were many more that I had only heard about. Then there were the ones that even this longtime OS/2 user and consultant had never seen before. Granted, this was a small room that three people could barely fit into, but the shelves were stacked from floor to ceiling, and there was much more downstairs where the real stock items were kept.
Oliver Minzloff himself is someone to meet. A friendly and reserved person who seems quite at home in his office that runs exclusively on OS/2, he's a retired artist who got into the business of distributing OS/2 applications more by accident than planning. He got started as a result of his frustration in not being able to get a well-known OS/2 word processor at what he considered a fair price. "I finally called DeScribe in the United States and asked them for a price based on the idea that I would be a distributor for them. They gave me a price that was about 1/3 of what I had been quoted in Germany." Once he got started as a distributor, his clients (who were grateful at being able to get OS/2 applications) started asking him what other packages he carried. He answered the question by asking what they were interested in. The rest, as they say, is history.
Minzloff data offers consulting services in addition to the products they carry. "We're more than just box movers," remarks Minzloff. "Most of our clients also want to know how and why a product is going to work for them. It's personalized service that goes a long with our products." That philosophy has helped Minzloff Data garner a following from all across Switzerland and a fair portion of Germany.
The company logo is a duck. For those who don't know the language, the German word for duck is "Ente" (pronounced En-Te). Of course, the word naturally gets mispronounced as "En-Tee". A little more trivia reveals that Ente is also German slang meaning a piece or a source of bad or misleading information. "This part makes the joke complete!" Minzloff quietly chuckles as he adjusts his glasses on his face.
Minzloff is realistic about his business. He's thriving in an environment where he constantly fights the notion that "everybody" is moving to Windows and NT despite numbers to the contrary. Like most people who use OS/2 at home, there is that classic love/hate relationship with IBM. "Warp 4 is the best version of OS/2 by far," he says. Then comes the frustration that we all feel that IBM just doesn't seem to be willing to tell the world with any kind of abandon, deciding instead to concentrate on their corporate customers. Still, there is more than enough business to keep him and his associates busy. It's the kind of place that really makes you wonder what IBM could do if they decided to play to the entire PC market as loudly and fully as the competition. How many more Oliver Minzloffs would pop up all over the world?
If you'd like to drop by Switzerland's exclusive OS/2 shop, make your way to Basel's main train station. Jump on the number 1 or number 8 tram headed towards Aeschenplatz. Get off on the 3rd stop (Barfusserplatz) and walk up the side street past the 50-50 Restaurant and the Cafe Barfi. Look for the window full of OS/2 applications and the wooden door with "Minzloff Data" and the small duck logo on your right.
Traveling through cyberspace might get you there a little faster. Direct your browser to http://www.minzdat.ch/ and you'll be there.

Exploring Warp 4's Manifold Offerings - by Larry Ayers
----------
Introduction
When I eagerly opened the new Warp 4 box a couple weeks ago I was a little overwhelmed by the quantity of software included. Luckily I had recently installed a larger hard disk so I had plenty of room in which to install the various packages.
Unfortunately, the documentation for Warp 4 is sorely lacking in several areas, so I have decided to share some of my experiences with installation and use of several of the pieces of software which came in that box.
Optional Components of Warp Itself
Installing Warp 4 can be quite an involved and lengthy installation, especially if you aren't using an Ethernet or LAN connection to a network. My sole network connection is a heavily-used dialup PPP link to my ISP, and I found that it wasn't apparent just which of the various networking components I really needed. I'm certain that there are several entries in my CONFIG.SYS file which load unnecessary drivers, but as of yet I haven't found the time to track them down. This post-installation tinkering shouldn't be necessary with Warp; I get my fill of that in my Linux partitions.
I can't really comment on the VoiceType feature, as my 80 MHz 486 groans and labors while attempting to run it. One of these days I'll spring for a Pentium board...
The integrated Java support has worked really well for me. I was rather disappointed that the WebExplorer 1.2 which was installed with TCP/IP doesn't support Java, though the Netscape Navigator beta's support makes this rather easier to tolerate. Bear in mind that Navigator's Java support is not enabled by default; it needs to be activated in one of the Preferences screens. Navigator's ability to download and run applets from the Internet seems roughly comparable to that of the Linux port.
Last spring I installed a beta of the Java Developer's Kit and tried it out for a few weeks, off and on. The version included with Warp 4 shows substantial improvement and the version shipping with beta 2 of Navigator is even better. The real test for Warp's Java support will be when actual cross-platform Java applications begin to arrive.
The OpenDoc package I found to be cryptic; just what is this intended to be used for? I realize that IBM is trying to encourage developers to make applications "OpenDoc-enabled", but the times I've tried to actually create a document with OpenDoc I've gotten unhelpful error messages which the Help documentation hasn't helped me understand.
Demos, etc. on the Application Sampler CD-ROM
I can not even begin to review all the applications on the CD Sampler. To list just a few, there are:
o Alphabet Zoo
o Back Again/2
o Clearlook
o DeScribe
o DeskMan
o Galactic Civilizations 2
o NeoN
o Object Desktop
o Partition Magic
o PhotoSuite
o SimCity 2000
o UniMaint
o StarOffice
o WebExtra
Again, that is just a fraction of the sample programs included. Below, I'll mention a few that caught my eye and that I found particularly interesting.
Lotus Word Pro '96
The Lotus Word Pro demo (an uncrippled beta dating from last June) worked pretty well for me. Though it is slow to load and rather ponderous in executing tasks, it did all that I asked it to, from loading Word 6 files with copious graphics to printing out heavily formatted and font-laden text. This is one of the first Windows-to-OS/2 ports compiled using IBM's new DAX libraries or Open32 as they are now known, and as such it is interesting to compare it with native-compiled OS/2 applications, such as Clearlook, which is a speed demon in comparison.
The help system is well done and complete. I did notice that when scrolling text, video artifacts (one-pixel-wide vertical lines extending out of the program window) were very apparent. Clearlook does this occasionally, although on a much smaller scale. (It's possible that this is unique to the S3 video driver I use.)
ColorWorks
The ColorWorks version 1 demo is great fun to explore. I'd never used ColorWorks before and found it impressive. This demo version will doubtless gain SPG some new customers. The save facility is disabled, as is the ability to load images not included with the program. SPG includes a varied selection of images, though, giving the user ample scope for experimentation.
American Heritage Dictionary
The American Heritage Dictionary has suffered from a buggy initial release and a resultant unfavorable review in OS/2 Magazine. The "Concise" version 1.2 offered as a fully functional program on the CD is a really useful and well-behaved utility. The dictionary is smaller than the one included in the commercial version, and there is no thesaurus, but the program is easy to use and even includes an anagram-search facility. I believe DUX Software will benefit in the long run from this approach. Of course there will be users who will continue to use the "light" version and never even consider paying for the full version, but those with the need for a higher-powered dictionary will be left with a good impression of the program's quality; I know I'm thinking of buying their product!
The Device Driver CD-ROM
The Device Driver CD-ROM is a great idea; if something like it had been included with Warp 3 life would have been easier for many new Warp users late in 1994.
The CD is well organized, using HTML files as an indexing and retrieval utility. I haven't needed any of the drivers yet, but it's a good feeling to know that if I buy additional hardware it's likely that what I would need is on this CD.
Another advantage of using HTML as the access method is the possibility of including URLs for some of the hardware suppliers' web sites. In effect, this causes the CD-ROM to be self-updating.
Conclusion
Many of the better-known and well-established programs included on the Sampler CD, I elected not to discuss here, as they have already been well-reviewed in the pages of OS/2 e-Zine! and elsewhere.
Aside from the lamentable lack of documentation in the Application Sampler CD-ROM, IBM has done a good job of providing an overview and introduction to just what is available now for OS/2. This material would be invaluable for the beginning OS/2 user, and even for an OS/2 veteran.
-----
(layers@vax2.rainis.net) Larry Ayers lives on a small farm in Northeast Missouri, where he operates a portable bandsaw mill and does general woodworking. He has been running OS/2 since the release of Warp 3.
Well, my unofficial Warp 5 FAQ web page has generated quite a bit of excitement so I was asked and decided to write a column based on my "findings". This column will not be a straight "port" of the web page but more an add-on with more comments and such.
Anyhow, "the news of my demise is greatly exaggerated": no that is not for Warp 4 but for OS/2 for the PowerPC (OS2PPC). We all have heard that the product is "put on hold" for 1997 and that there are no machines available to run it on.
All this might be true, but every time news on Warp 4 or Warp 5 lands in my e-mail inbox, it smells OS2PPC. Many of the features touted to be new in Warp 4, 4.x and Warp 5 have been available in OS2PPC since its release. And yes there have been several FixPaks for OS2PPC adding even more new features.
The bottom line is: If you want to know where OS/2 is heading, take a look at the specs for OS/2 PPC. Warp 5 will be based on the OS2PPC code. That does not mean that features won't be added to Warp 4, but they will be mostly cosmetics. OS2PPC has a TRUE asynchronous input queue (no WPS hangs). It has multithreaded device drivers (promised for Warp 4.1) and even object oriented device drivers that greatly simplify development and porting of device drivers. Now, don't run out to get a machine and start bugging IBM for OS2PPC, Warp 5 will be different, not just because it's a later release, but also since two important things have changed:
The microkernel (MK) will be replaced with version 2.0. The microkernel (IBM (Mach) Microkernel 2.0) has nothing to do with OS/2. It's used in various IBM and non-IBM projects and I suspect that future AIX versions and even the AS/400 will be based on it. The MK is the thing that handles the hardware interface for the operating systems that runs on the machine. IBM has shown a PPC machine running Windows NT and the Macintosh OS concurrently and that was probably on top of the MK. The new MK is better and faster and more portable than the old one.
Warp will also become Server/Client. This has fooled people into thinking that OS/2 will be turned into a Server only OS. What it means though, is that both the client and the server will share the same codebase. Why don't we call Windows NT 4 Workstation dead? It is also developed with this method. (It's even rumoured that you are able to upgrade your Windows NT Workstation to a Windows NT Server by just changing settings in its registry.)
Oh, yes, OS2PPC has a registry also, no more CONFIG.SYS/OS2.INI/OS2SYS.INI etc. in Warp 5. This seems to be an important change for IBM. Even Warp 4.1 is rumoured to be built in a Server/Client method.
Warp 4.1 has been in alpha for more than a month now and there is a projected release date at the end of the first quarter of 97. What features will make it into this release is unclear and we should not be surprised if there is a Warp 4.2 in autumn (with the features that did not make it in 4.1). IBM is not very clear on how the new release will be delivered. It might be free (as a "FixPak" for Warp 4) for download from the Internet. Due to the size of things nowadays lets all hope for a shrinkwrapped package!
Warp 5 is projected to be ready in the first quarter of 98. Warp 5 is still on the drawing board so don't expect IBM to keep that projection! They will probably try to coincide with Windows NT 5.0 whenever that will be ready. Warp 5 is supposed to be portable, that is, easy to implement on different platforms. Expect at least Intel, PPC and Alpha (DEC) versions.
Of course, all the above are speculations. While they most likely are the things that IBM is currently working on, there is a reason that IBM does not discuss these things in public: they might change their minds. No, not on their support for OS/2, but Warp 5 may be released in the fall with full Windows 95 support. Who knows...

NetHead's Nook - by Brandon Fesler
----------
Ahhh, welcome once again, dear reader, to another edition of NetHead's Nook -- a place, if you will, of utter placement. What I mean is that my job is to put people in their place. After all, isn't that what satire and commentary is all about?
I'd like to take this chance to wish all of my beloved readers a wonderful holiday season, a very merry Christmas, and a splendid new year. I hope that everyone enjoyed Thanksgiving, and had plenty to eat. I know that I did; I'm now more stuffed than the turkey was.
So... last month I promised you a triple sized column, and here it is, once again, positively the LAST thing you need. So, go right now and get a cup of tea or coffee and prepare to come back and dive into a large sum of interesting commentary and satire. I'll wait...
Ok. Now that you're back, we shall begin.
First off, on a serious note, I'd like to send my kudos to the people at Netscape and IBM who have been working on Netscape Navigator for OS/2. The second beta really is a very stable and usable program, and surprisingly, can seamlessly use Windows 3.1 plug-ins for Navigator just like it can use OS/2 plug-ins. Once again, OS/2 gets all the choices. (But then, what else is new?) Netscape has been on the wish lists of many OS/2 users for a long time, and this high-quality port has been well worth the wait.
And now, on a less serious note...
Well, our friends in Redmond are back at it again, so the next few paragraphs will be focused on them. Hey, you can't blame me... they're such easy targets! For example, it appears that Microsoft is trying to get sole coverage of the Olympics in the year 2000, for MSNBC. Apparently things aren't going too well yet. When a poll was taken of their proposed slogan, "What do you want to throw today?", most of the surveyed people took it as a software question, and the athletes they polled thought Microsoft was about to start selling pain relief creams.
Now, if that wasn't enough, it seems that after spending four-hundred million dollars on Internet Explorer 3.0, MSNBC, and Expedia, Microsoft is declaring to the world that the Internet isn't a money-making business. Oh yeah, right, sure. Yep, I believe you.
And, last but not least with our friends from Monopolis -- AKA Redmond, WA -- is some interesting information about ActiveX (called CaptiveX by many). Lots of people are bringing up concerns about ActiveX's security flaws, namely, the fact that there is no security. Well, this figures. The only people who are more thrilled about ActiveX than Bill Gates are the people who write 90% of ActiveX controls... ACiD, PHReaK, RaNCiD, and DeTHZoNe.
In other news, Java is taking off big time (no surprise here). Recent figures are showing astounding development rates... some showing 50% or more of major software houses are currently porting or developing for Java. What does Microsoft have to say? Well, we weren't able to e-mail their spokesperson, as it seems he had just visited an ActiveX enabled web site and was having to reinstall Windows 95 and all his programs.
Well, OK, that's enough Monopolis news for today. It's time to join me once more for yet another original NetHead parody song!
"I am the Lemming" by NetHead

With MSN icons, why should AOL have a voice?
Office 97 will be my top player
Till MS releases API specs some 9 months later!
Yep, I'm sitting pretty waiting for this to come
While those idiots using OS/2 idly just get work done.
But I only dream about using 97 at this time
Cause it's not coming out till Mid-'99!
VALUABLE COUPON!
Take this to any convenience store for one free dollar.
If the cashier gives you that dollar, be sure to
tell me which store it was... I have yet to make this
coupon work in my area.
Oh no! Here comes YET ANOTHER original NetHead song.
Throwing My Windows Out
(To the tune of 'Wearing the Inside Out' by Pink Floyd,
on The Division Bell compact disc.)
From morning to night I sweated with fright
My PC had not much use left
No more than alive, my system spoke jive
In a word... GPF
(lead singer) (backup singers)
And when it broke The system is now failing
Suddenly And the screen is flickering
What I did then Thanks to that Windows garbage
Changed history ...once again
My skin grew cold I'm running from the mainstream
My breath grew light The self-destructing animal
I threw Windows It's killing my productivity
Out that same night I'm moving up
I went to the store and searched round there for
Something that would end my senseless bind
Then came the light, and there in my sight
A Warp box, with its BonusPak behind
My systems back to life
My CPU is now alive
I'm throwing my Windows out
Got Merlin now
It's stronger somehow
And it's getting better
It's hearing my speech
Nothing is out of my reach
And I can dictate stuff right from my mouth
And all these words it can hear
It knows my speech and gets it clear
I speak my mind and then rejoice
I get around with just my voice
(lead singer) (backup singers)
I'll use 4-0 He's using the best OS
Till the day He has made the wise choice
When Bill Gates is And hurled into the future he'll
Out of my way ...curse Bill Gates
If that were now He's no longer a lemming
No more crash pain And the screen's not flickering
And we could use Waiting is not OS/2's way
Our choice again
(My apologies for the extra Microsoft bashing this month. Oh well, it's not like anyone was offended. Right?)
Until next time, please enjoy this holiday season!

The Chronicles of (dmccoy@mailhost.mnsinc.com) John Ominor - by (dmccoy@mailhost.mnsinc.com) John Ominor, The Inhuman
----------
You are all on the cusp of an new era, and I, (dmccoy@mailhost.mnsinc.com) John Ominor, will lead you, kicking and screaming, if need be, into it. Even now, (dmccoy@mailhost.mnsinc.com) Ominor prepares to release a set of initiatives to use in this the new order.
Behold... The SynthoGlatt.
"But, Mighty One," you inquire, "What is this creation? I do not understand." Of course not. You are not The Inhuman. (dmccoy@mailhost.mnsinc.com) Ominor will now explain. Humans are imperfect. Weak. Inflexible. Incapable of even the most basic tenets of reason. Worst of all, once a human is created, it is difficult to modify his behavior... to extend and improve upon it. Would that Homo sapiens were object-oriented.
(dmccoy@mailhost.mnsinc.com) Ominor has addressed all these shortcomings and more by starting from scratch. First, The Inhuman has constructed a new object framework upon which to base the Homo sapiens. Next, The Inhuman introduced the PAPI, or Personality Application Programmer's Interface, a new means by which (dmccoy@mailhost.mnsinc.com) Ominor's creations can be more easily modified.
The first of this new line of better individuals is, of course, The SynthoGlatt. Spawned from the Yeast Vats of The Inhuman Labs, The SynthoGlatt will be the cornerstone, the linchpin if you will, of the new order. Imagine, thousands, nay, millions of synthetic men vomited ad infinitum, from the Yeast Vats, created for the sole purpose of furthering the cause of (dmccoy@mailhost.mnsinc.com) Ominor; thereby, aiding all of mankind.
The world's first truly disposable man, The SynthoGlatt, will be able to perform tasks too menial or hazardous for humans, such as toxic waste disposal, plutonium granule sorting, or even replace those beloved crash-test dummies for truly accurate results. It shall not be unheard of to engage in such idle pursuits such as determining how many SynthoGlatts it will take to fill The Sun.
How can (dmccoy@mailhost.mnsinc.com) Ominor afford to create so many SynthoGlatts you ask? Volume. By creating an endless supply, (dmccoy@mailhost.mnsinc.com) Ominor will keep the cost per unit to well under .000000001 cents.
The mind beckons. The body follows.
My army of SynthoGlattic sub-men will mean the birth of a truly unstoppable fighting force for world peace. No matter the weapons, no matter the tenacity demonstrated by the enemy, (dmccoy@mailhost.mnsinc.com) Ominor's endless legions will be a truly relentless, irresistible power. Armies can bomb them. Gas them. Burn them. Vaporize, atomize, or pulverize them and The SynthoGlatts will keep coming. They cannot be reasoned with. They do not feel pity or remorse and they absolutely will not stop until (dmccoy@mailhost.mnsinc.com) Ominor's truly benevolent will is imposed upon all of creation.
(dmccoy@mailhost.mnsinc.com) John Ominor will now educate all with a fable... There was once an old human who had five male offspring. Like most humans, these individuals wasted a significant portion of their time fighting amongst themselves instead of striving to better serve The Inhuman. Finally, weary of their abrasiveness, and hoping (dmccoy@mailhost.mnsinc.com) John Ominor himself would not step in to settle events in such a way that would surely be disliked by all, save (dmccoy@mailhost.mnsinc.com) Ominor, the paternal human summoned his seed and gave each a stick. "My son," said the patriarch to the eldest, "break the stick." He did. And quite easily, even for a human. The father then beckoned each son in turn to do the same and each did. The sticks were destroyed.
Most impressive.
Next, the father gave the first son five sticks bound together. "My son," said father, "you know the routine. Break the sticks." The son could not. Nor could his brother nor their brothers after him. All five sons failed miserably. How weak the humans were, failing to break small shafts of wood held together by string. Surprisingly, the father's lesson was not to teach his sons how pathetic they were in comparison to (dmccoy@mailhost.mnsinc.com) John Ominor; instead, it was to teach them that separate, they were weak, but together, they were strong, except in the presence of The Inhuman.
Imagine, if you will, five SynthoGlatts tethered together by a sixth SynthoGlatt would possess a tensile strength greater than that of even a steel girder. Perfect for the construction of new buildings and bridges. Why, by stacking SynthoGlatt after SynthoGlatt, one on top of another starting at the bottom of the ocean, it would be possible to create man-made islands.
Soon, from the stuff of dreams, reality will take shape such as mortal man has scarcely dreamt...
Next time... The Truthbot cometh!

The origins and current plans of (dmccoy@mailhost.mnsinc.com) Ominor are known only to (dmccoy@mailhost.mnsinc.com) Ominor. He is indeed a mystery to all. Save The Inhuman.
