Archive X-Ray Programs 1.03 AR 1.11 (ARJ) LR 1.02 (Lharc) ZR 1.27 (ZIP) ZOR 1.01 (ZOO) Copyright 1990 - 1993 by Gordon Haff and Bit Masons Consulting. All rights reserved. Command: ZR or AR or LR or ZOR Purpose: Provides a scrollable environment for selecting files contained within a ZIP file and viewing or extracting their contents Syntax: ZR [d:][\path\]filename.ZIP [/n] Commands: <Enter> views files <Space> extracts files <d> deletes files <esc> to exit Prereqs: 100% IBM Compatible PC running DOS 3.0 or higher Archive Name: XRAY103.ZIP Associated Programs: In their default configuration, the programs REQUIRE Vern Buerg's LIST file viewing program (or 4DOS with LIST as the viewer name) and the corresponding archive program (PKUNZIP, LHA, ARJ, or ZOO). LIST, PKUNZIP, 4DOS, and ARJ are Shareware and either require separate registration with their authors or request a donation. See the individual program license agreements for details. AR also requires the included UNARJXR, a slightly modified version of Robert Jung's UNARJ to which he retains full copyright. While these programs can be operated from the DOS command line using the format described above, they are most conveniently called as a user-defined shell command (or SmartViewer in DF 4.0 and later) from within the author's Directory Freedom (DF) program. PC Magazine's PATCH program is included together with PATCH information files for modifications. See PATCH.DOC for usage information. Other: Your COMSPEC variable must be set. See Section 2.1.

X-Ray 1.03 4 1.0 Why and Whence the X-Ray Viewers? ---------------------------------------- The main reason that I originally wrote Z-Ray (as in Zip X-Ray) is the following: I have a shareware file management program called Directory Freedom which is small and fast in spite of having more wonderful and exciting features than I could possibly describe here (Plug #1). Yet, there was still one thing which I continually ended up having to exit DF to do -- namely, to view the contents of files contained within ZIP files. This annoyed me. I looked high and low for a program which I could call with DF's nifty user-defined shell function (Plug #2), but nothing did exactly what I needed. So out came the assembler and, a week or so later, out popped ZR. As time passed, I also wanted to be able to do the same thing with other archive formats I sometimes used -- ARJ and Lharc. So, taking Z-Ray as a base, I wrote AR and LR. These latter two programs do work a little differently (inside) from ZR -- see the Technical notes -- but these differences should generally be invisible to the user. So.... armed with these viewers, DF can now perform most of the major archiving and de-archiving functions for the major formats used on PC's. (DF 4.0 and later has the capability to archive files.) For the fancy stuff (such as selective archive updates), you'll still need a program like ARCMASTER or SHEZ, but DF will be able to handle all the everyday stuff. X-Ray 1.03 5 2.0 How does it Work? ------------------------- I'm glad you asked that question. It works incredibly well. Oh.. HOW does it work. Well, there's nothing to it. (Note: The rest of this section just shows ZR. There are no differences at the operational level between ZR and the other programs. Just substitute AR (for ARJ files), LR (for Lharc files), or ZOR (for ZOO files) if you are using one of those formats.) The command line syntax is just: ZR [d:][\path\]filename.ZIP [/n] So, any of the following are valid: ZR TEST.ZIP ZR C:\FOO\TEST.ZIP ZR E:\FOOBAR.ZIP /n You do need to type the extension since ZR will look into any file with a ZIP format (including self-extracting files). /n (or -n) will sort the list in ascending alphabetical order. Assuming the specified file exists and is valid, you'll get a window on the screen which looks something like the following. The top line in the directory will be highlighted.

You can quit by hitting the <Esc> key. And now we come to the useful part -- you can view the contents of a file by pressing the <Enter> key. What the <Enter> key does is pipe the contents of the highlighted file to Vernon Buerg's LIST program. PKUNZIP and LIST MUST BE PRESENT IN YOUR PATH OR THIS WON'T WORK!!! Later on, I explain how the default command line can be changed in case you've renamed LIST or know some other way to do the same thing. The default exec line is: PKUNZIP -c ~ ` | list /s where: ~ is the name of the archive being viewed ` is the name of the selected file These names are filled in dynamically by ZR. The command lines differ for AR, LR, and ZOR. See the customization section. But Wait! There's more! You can also EXTRACT the highlighted file. Pressing <space> or e will extract the highlighted file with the following default command line: PKUNZIP ~ ` As with the viewer, this function requires that PKUNZIP be present in your path. The extraction will take place to the current DOS directory. Finally, pressing d will delete the highlighted file. About the Totals line: The totals line on the bottom gives you some summary information about the archive -- total files, uncompressed and compressed bytes, compression percentage, and PKZIP version number (in the case of ZR). The PKZIP version number is the oldest version of PKZIP which was used in creating the archive. USUALLY (as in almost all of the time) all files in an archive will have been archived using the same version, but this isn't necessarily the case -- files can be added to an existing archive and the versions don't necessarily have to match. X-Ray 1.03 7 2,1 COMSPEC Variable. ---------------------- In order for any of the X-Ray viewers to work, your COMSPEC environment variable must be set. This variable tells ZR {AR,LR,ZOR} the name and the location of the command interpreter to use when it shells to the appropriate archive program. Without a COMSPEC variable, ZR will display a file listing, but you will be unable to view the contents of files. AR, LR, and ZOR will not even get this far since they depend on the archive program itself to generate the file list. To set the COMSPEC variable, include a line such as: SET COMSPEC=C:\COMMAND.COM in your AUTOEXEC.BAT file. The above example is typical for a hard disk system but other COMSPEC lines such as: SET COMSPEC=C:\4DOS.COM and SET COMSPEC=\COMMAND.COM are also possible. The former uses J.P. Software's excellent 4DOS as the shell and the latter uses COMMAND.COM on the current logical disk (This would be common for a floppy-only system). You can view your environment settings at any time by typing SET at the DOS prompt. (Actually with recent versions of 4DOS, it probably isn't necessary to set a COMSPEC since 4DOS is smart enough to use an intelligent default. Still, it doesn't hurt. And it MUST be set if you use the standard DOS COMMAND.COM shell.) X-Ray 1.03 8 3.0 Customizing ZR, AR, ZOR, and LR. ---------------------------------------- (NOTE: See PATCH.DOC for information on making modifications using the ZIF patch information files.) I haven't gone and written a fancy user-friendly configuration program for these programs, but you can do some limited modification if you have a hex editor of some sort such as Norton's DiskEdit or NU. Debug will also do in a pinch for the more adventurous. MAKE ALL MODIFICATIONS ON A COPY! ALSO -- make sure that the rev of the program matches this documentation since the offsets could change between revisions! Colors: ------- Variable Offset Default -------- ------ ------- C_NORMAL 0Eh 02h C_INVERSE 0Fh 74h C_INTENSE 10h 03h C_BORDER 11h 4Eh C_BORDER is the attribute for the window border, C_INTENSE for the heading in the window, C_INVERSE for the bar. The color values are in standard DOS combined foreground/background format. See the Appendix for details on the values you can enter. The value at offset 12h can be changed from a 0 to a 1 to disable the archive file delete function. Command Lines: ------------- The default command line for the viewer is: ZR: PKUNZIP -c ~ ` | list /s AR: ARJ p ~ ` | list /s LR: LHA p ~ ` | list /s ZOR: ZOO -p ~ ` | list /s and resides from offset 16h through 33h, padded with spaces (20h). (These offsets, like those for the colors, are relative to the beginning of the file at 0000h.) If you modify this command line, be careful not to overflow the space allotted to it (there's a NULL (00) on the end) or the results will likely be very unpleasant. X-Ray 1.03 9 The default command line for the Archive extract is: ZR: PKUNZIP ~ ` AR: ARJ e ~ ` LR: LHA e ~ ` ZOO: ZOO -e ~ ` and resides from offsets 38h through 55h. The default command line for the Archive delete is: ZR: PKUNZIP -d ~ ` AR: ARJ d ~ ` LR: LHA d ~ ` ZOO: ZOO -d ~ ` and resides from offsets 5Ah through 77h. In addition, LR, AR, and ZOR specify a command line which extracts the archive file list information to a temporary file. The equivalent line does not exist in ZR because ZR does its own decoding of the archive. The default command line for this is: AR: UNARJXR ~ > xr99tmp LR: LHA ~ > xr99tmp ZOR: ZOO VC ~ > xr99tmp and resides from offsets 7Ch through 99h. The temporary file name, which must match the name in the above command line, resides from 9Bh through A8h. X-Ray 1.03 10 4.0 Configuring DF to use ZR: -------------------------------- This is also very easy. Just configure SmartViewer lines (using DFCONFIG) to read: Command line Extension ------------ --------- ZR ~ ZIP AR ~ ARJ LR ~ LZH ZOR ~ ZOO When you highlight an archive file with DF and press the <Enter> key, you will pop directly into the file listing window of the appropriate utility from which you can select files to view. No file names to type! Isn't that easy? Of course, you can also setup standard user-defined function keys if you wish.) 5.0 Technical and Acknowledgments. -------------------------------------- ZR does its own decoding of a ZIP archive file by reading in the central directory structure. It will read all versions of PKZIP archives up to and including at least version 2.04g. I strongly recommend that you do NOT use PKZIP/PKUNZIP 2.04 versions prior to 2.04g. LR, and ZOR on the other hand, create a temporary file which contains the contents of an archive listing generated by the archiver itself. This archive listing is then parsed into the appropriate format for the scrollable display. The programs were developed using Lharc (LHA) 2.10, and ZOO 2.1. Differences in the archive display format in either program could therefore cause difficulties. AR does something similar but because of some problems caused by changing formats, it uses a modified version of ARJ's demo viewer to generate the listing. One of these days, my goal is to write native mode decoders for at least ARJ. ZR, AR, ZOR, and LR were written using Borland's Turbo Assembler 3.0 and Turbo Debugger 3.0, American Cybernetic's Multi-Edit 6.0, and Base Two Development's Spontaneous Assembly assembler library 2.0. The hardware environment was a homebrew 386 (named Dejah Thoris) based on an AMI 20MHz full-size motherboard with a Micropolis 160MB ESDI disk and Ultrastore 12(F) ESDI controller. It is a dual monitor system with an Orchid Prodesigner 512KB VGA board and an IBM MDA board. Last, but certainly not least, thanks to my Directory Freedom beta crew who have also helped out in debugging ZR as well. X-Ray 1.03 11 6.0 Other Programs from Gordon Haff and Bit Masons Consulting: ----------------------------------------------------------------- Directory Freedom (DF): Offers users a fast, compact alternative to DOS Shells which provides 1) selective file and directory operations; 2) a scrollable environment for examining files and directories; 3) user-defined keys which can operate upon highlighted files (e.g. by defining an editor). All this in a program which takes less than 35KB since it is written in assembler! Easily customized through an external configuration program. A "look- and-feel" similar to PC Mag's DR, but does much more. Now with SmartViewers, a system information screen, and many more exciting new features. Shareware: $25 Registration Latest version: 4.61 (DF461.ZIP) the last word: 'the last word' is a quotations trivia game in which 1 to 4 players compete against each other and their own high scores in identifying the source of quotations and completing partial quotes. Most answers are entered free-form and are matched against a set of acceptable responses with a sophisticated pattern-recognition algorithm. 'the last word' runs in text mode -- including on mono displays -- and offers a high level of user configurability. Shareware: $15 Registration Latest version: 1.00 (LWORD100.ZIP) Name Date: Renames a file to a template such as the current date. In other words, if the current date were 10-06-90, the file 'FILENAME.QWK' would be renamed to 901006.QWK. Version 2.0 is highly configurable with many command-line options including the complete specification of the format template to be used for renaming. This is a handy program for archiving message packets from bulletin boards, for example. Free, copyrighted software Latest version: 2.0 (NAMD200.ZIP) X-Ray 1.03 12 Convert: Unit conversion calculator for Windows 3.1. Comes with a data file containing a large number of common (and not so common) conversions in categories such as length, speed, pressure, volume, and time. The data file is a plain ASCII text file so the user may add or delete units to best fit his individual needs (or use the built-in editor). Version 2.01 is a complete rewrite from version 1.01 and has a whole new look and many new features. Shareware: $15 Registration Latest version: 2.01 (CVT201.ZIP) Volume label Edit and Copy: Edit, delete, and copy volume labels. Will use absolute disk read/write operations as required to deal with "non-standard" volume labels such as those with lower case characters. The Copy function could be used as part of a batch file to backup distribution disks to a different sized floppy. Free, copyrighted software Latest version: 1.10 (VEC110.ZIP) MAKETEST: Command-line utility to create test files. Lets you create any number of test files with user-specified names and sizes. Automatically can add characters to avoid duplicate names. This is an easy way to create something like 100 zero-length files. Handy for users or programmers who want to test a program's capabilities. Free, copyrighted software with QB source Latest version: 1.0 (MKTST100.ZIP) These programs and others (Multi-Edit macros for use with Qmail Deluxe, for example) are available on many fine bulletin boards. The latest releases are always available on Channel One. If you just have to get a copy of one or more of these programs and can't find one, however, I can send them out for a nominal media and postage charge.

Rev. 1.10 Fixed display problem on monochrome systems Fixed problems with ZIP files < 10Kbytes Rev. 1.0 Initial Release AR: --- Rev. 1.11 Rev. 1.10 By using a modified version of the UNARJ extract program (called UNARJXR.EXE), AR can now handle a variety of ARJ archives it was choking on (Rev 2.30, environment settings, etc.) Rev. 1.01 Added delete archive file option Rev. 1.0 Initial Release LR: --- Rev. 1.02 Rev. 1.01 Added delete archive file option Rev. 1.0 Initial Release X-Ray 1.03 13 ZOR: ---- Rev. 1.01 Rev. 1.0 Initial Release 8.0 Known Limitations and Peculiarities: -------------------------------------------- (i.e. These are free programs and I got tired of beating out my brains over it for the time being.) All: ---- o The piping mechanism to LIST can truncate long files. Unfortunately, there is no warning that such truncation has taken place. ZR: --- o Truncates the display of files archived with their paths and will not pipe them to the viewer properly if the entire path and filename is greater than 13 characters. AR,LR: ------ o Will not handle paths o Rely on a specific file display format generated by the archiver (not really true any longer with AR) ZOR: ---- o As for AR, LR o Sometimes the file display as piped to LIST comes out double-spaced. I'm not sure of the reason for this, but it is not a function of ZOR; you will obtain the same result if you pipe an archived file to LIST from the DOS command line. X-Ray 1.03 14 APPENDIX A COLORS The color number stored for use in ZR, AR, LR, and ZOR are combined foreground/background attributes of the type used by DOS. This combined attribute value is simply the foreground and background numbers, as given below, bit-wise OR'd together. That's a fancy way of saying added together for our purposes here. (Remember though that these are hexadecimal numbers.) For example, yellow on a blue background is given by 1Eh (0Eh + 10h).
