The Comp.Sys.Mac.Programmer Digest is moderated by Mark Aiken
([e-mail]).

The digest is a collection of article threads from the internet
newsgroups comp.sys.mac.programmer.help, csmp.tools, csmp.misc and
csmp.games. It is designed for people who read news semi-regularly and
want an archive of the discussions.  If you don't know what a
newsgroup is, you probably don't have access to it. Ask your systems
administrator(s) for details. If you don't have access to news, you
may still be able to post messages to the group by using a mail server
like anon.penet.fi (mail [e-mail] for more information).

Each issue of the digest contains one or more sets of articles (called
threads), with each set corresponding to a 'discussion' of a particular
subject.  The articles are not edited; all articles included in this digest
are in their original posted form (as received by our news server at
ee.mcgill.ca).  Article threads are not added to the digest until the last
article added to the thread is at least two weeks old (this is to ensure that
the thread is dead before adding it to the digest).  Article threads that
consist of only one message are generally not included in the digest.

The digests can be obtained by email, ftp or through the World Wide Web.

If you want to receive the digest by mail, send email to
[e-mail] with no subject and one of the following commands
as body:

    help                        Sends you a summary of commands

    unsubscribe csmp                    Removes you from the list

Once you have subscribed, you will automatically receive each new
issue as it is created.

   Off the top of my head, 32 MB should be comfortable.  You could
     probably live with 24 MB, more is better.

For me and my 9500, I give CodeWarrior 5 meg, MPW 10 meg, Netscape 3 meg,
Apple Telecom 5 meg, OpenDoc ... I have 48 meg and am a bit cramped.
Probably 64 meg or more is nice and roomy.  If you want to do any
serious QuickTime/QuickTime VR authoring, you will want 96 meg to be
nice and speedy.  With large amounts of RAM, it is also possible to
create a big RAM-disk where temp files for builds can be placed (in MPW)_
which can REALLY speed up builds.  YMMV.

I would say that 32Mb is minimum. Some debugging tools require VM
and / or Ram Doubler to be off, which, if you are doing Speech Recog
or something, puts the System heap at around the 12MB mark. Then have
open your compiler, debugger, Netscape (to browse Inside Mac online),
and ResEdit, and you've run out.

BTW, I code and debug with RD installed with no problems. Just turn
it off to find those really pesky bugs with the serious debugging tools!

24 Megs at minimum. Forget using RAM Doubler if you're trying to debug
anything other than applications that do not patch the OS. Its not worth
the trouble.

My rec. for memory is is along the lines of 1950's consumerism- more is better.

I use every bit of 48 Mb of RAM since I have a lot of image processing
going on in my programming. This is for scientific work,but might be
important for games also--it just depends on your own needs,but as cheap
as RAM is, I see no need to minimize on such an important enhancement.

Subject: AppleScript Commands
Date: 4 Nov 1996 19:39:04 -0700
Organization: Primenet Services for the Internet

I'm trying to accomplish a lofty automation task, mostly in MiniPascal,
MiniCad's internal programming/scripting language.  That all works just
fine.  But for some of what I want to do, I need AppleScript, but I can't
find any documentation, and I'm in kind of a hurry here.  What I want to
do isn't really all that complex either.

I figured out how to "tell" MiniCad to open a certain file, signal it to
make the necessary changes, and even to send a "Print..." command.  But
not how to print 1 copy, or to close the file without saving changes.

"Print..." opens a dialog box, asking for the user to enter the number of
copies.  The goal is to print a large number of files automatically, we
don't want to have to hit return every minute or so for 3 hours as this
thing runs.  Is there a print 1 copy command, or a way to tell it to hit
"Ok" as soon as the print dialog comes up?  What about closing the file,
without saving changes?

Anyone who could either tell me the commands and proper syntax I need, or
point me to an online reference source, would be most appreciated.
Thanks!

You probably can't find a complete list since the commands are all built
into each application that supports AppleScript. Danny Goodman's
_Applescript Handbook_ is probably the closest thing I know to a list of
commands.

There is a Required Suite of commands that each scriptable application
must support which contains the open print quit and run commands. This
print command *only* does exactly what selecting a file in the Finder and
choosing the Print command.

To get more functionality, the application must provide it. To find out
what commands an application supports, select "Open Dictionary..." from
the Script Editor's File menu and find the application. The list of
commands is broken down into groups or "Suites," which lists the syntax
for each command. Most of the time I find it difficult to understand
exactly how to use each command because there is no example listed with
the commands.

Hope that helps,

Subject: FindAllResIDsInFileGivenResourceType() ???
Date: 4 Nov 1996 11:03:49 GMT
Organization: CMPSCI Department, UMass Amherst

I need to collect all of the in use resource IDs for a given resource
type in the resource fork of a file.  The "brute force" method:

    short curResFile = CurResFile();
        UseResFile(refNum);
        for (int ires = 0; ires < 32768; ires++)
        {
                Cell aCell;
                Handle resource = Get1Resource(LabelTemplate::labelResourceType$
                if (resource == NULL) continue;
                Size s = GetHandleSize(resource);
                DetachResource(resource);
                DisposeHandle(resource);
        /* some processing */
        }
        UseResFile(curResFile);

is obviously not the solution.  There does not appear to be a function
that returns this information, at not that I can find.  ResEdit (and
DeRez) obviously can do this, but what is the magic?

Robert,

you can use CountResources / Count1Resources to get the number of
resources of a given type and then call GetIndResource / Get1IndResource
in a for-loop to read the resources by index.
These routines are documented in Inside Macintosh: More Macintosh Toolbox.

May it help,
Roger

Look for Count1Resources() and GetResInfo().

    short   numResources    = Count1Resources('????');
    Handle  h;
    short   rsrcID,
    ResType rsrcType;
    Str255  rsrcName;
    short   index;

    SetResLoad(false);

    for (index = 1; index <= numResources; index++)
    {
        h = Get1IndResource('????', index);
        GetResInfo(h, &rsrcID, &rsrcType, rsrcName);

        /* do processing */
    }

    SetResLoad(true);

Two things to note:

    The index starts at one (1), not zero (0).

    By calling SetResLoad(false) the resource is not actually loaded into
    memory - you only get a non-empty handle if it's already in memory. This
    cuts down on the time taken.

No.  You're better off using the Infinity Windoid, available from any

Only floating palette WDEF is included with System 7.5, that is you get
the _look_, but not the behavior of a floating palette. If your app will
run only on System 7.5 or later, you have a start, otherwise you'll need
to get a floating palette WDEF for pre-System 7.5 apps. The Infinity WDEF
is a good selection.

You have several options to make the window _behave_ like a floating
palette:
  1. Use a class in Symantec's TCL
  2. Use a class in Metowerks' PowerPlant
  3. Use Tools Plus application development libraries
  4. Roll your own code (not a good option)
  5. Wait for MacOS 8

BTW, you can get a free evaluation kit of our Tools Plus libraries at our
web site, or just take an illustrated Tools Plus Guided Tour. Tools Plus
lets you create any *working* GUI element with 1 line code, including
tool bars, picture buttons, pop-up menus, etc. It also makes dialogs and
menus work with a single line of code. Rate 4 stars by Macworld magazine.

Date: Fri, 04 Oct 1996 19:23:57 GMT

Hi there...

I'm currently running a PC system and have a need to send files to a Mac
using zmodem... I didn't reaslise that the Mac needs an 'extra' little bit
called the resource fork. To make matters worse, I don't have access to any
of the Macintosh machines I'm sending files to...

Does anyone know how I can create a graphic file using Photoshop on a PC
and 'alter' it in some way to so that I can send it to a Mac, WITHOUT
having to alter the file on the Mac itself (i.e. using resedit...)

It's really important that users on the Mac don't have to perform any
alterations to the file once they receive it. IT MUST look like it was
created on another Mac!

There has to be a little utility to do the job.

Anyone know if one exists....?

One way (easiest i think) is to do a raw binary transfer and
setup zterm on the mac to set the file type correctly,
thats all. There should be no resource fork to your graphics
files.  If you really have no acess to the mac you have a tough
problem - if the user cant set the type how do you know he
doesn't have it in text mode for that matter.

Another way, maybe easier for the mac user, is to do a macbinary
transfer. Then on the pc end you need to prepend the macbinary
header to the graphic file before sending.  I'd be suprised if
there isn't a little dos utility to do that (hunt your favorite
archive)

When will all you mac users understand that comp.os.mach isn't about macs? I
mean, why on earth do you think it's called mach? And the fact that other
mac groups are called comp.sys.mac.something, should make you think twice
before posting in a comp.os.something group.

(For all the people who still don't get it. Mach is a microkernel. Sure
there are ports of mach for macs (mklinux etc), but that doesn't mean that
we want stupid macintosh questions here...)

Don't make things to hard for yourself.  Don't send it as a Photoshop
file, but as one of the standard graphic formats (Tiff, bmp, etc) which
the Mac Photoshop will quite happily open without needing a resource fork.

Word 6.0 files are able to be read between the Mac and PC platforms

AND remember that EPS although it exists on both platforms are
different in structure. There are programs that will convert but you
usually looses the preview.

I didn't think Photoshop had a problem with it's own format cross-platform.
i can see where the resource fork can be an issue in files such as .eps
or.qxd, but Photoshop?!?  could it be that the inquirer is trying to copy a
file from the PC to a Mac via floppy? this can confuse the app of the Mac
into beleiveing that the file is just a "document". I have copied
Illustrator files in this manner and have used the .ai . Illustrator will
not see them as Illustrator files because they don't have the type and
creator.

However I can agree with you though, that the use of tiffs pr bmps may be
the best because I have had photoshop launch when double-clicked on.

PC Exchange may be helpful here also. It can be configured to recognize the
files by their extensions and rebuild their resource forks.

Actually, it's stored in a DSAT resource. And be careful modifying it; the
string must be the same length (or you must change the lengthy and pad or
remove bytes as necessary to keep the resource the same size and the
string at the same offset and not overwrite any other data.) A little
slipup will cause your Mac to crash at startup.

There are programs out there that will do this for you. I don't remember
the name of any of them, but someone else here surely does.

Also, the "Connectix Ram Doubler" string is RAMDoubler's doing. So you'll
have to come up with a separate hack for RAMDoubler.

You can replace that little phrase with one of your own, or with none at
all. Begin by making a backup copy of the RAM Doubler extension, which you
can do by option-dragging the original from the Extensions folder to the
Startup Disk icon. Then use Apple's ResEdit utility to open the original
RAM Doubler, and in the list of resource types that appears, double-click
the DSAT type. Open the only DSAT resource, ID -4064, to see its contents.
Then find the message on the right side of the resource-editing window,
select it, and type a replacement (see "RAM Doubler Start-up"). Save your
changes and restart the Mac to view your handiwork.

There is a nice little program, Errditor, which lets you edit the
startup messages. It won't let you change the Ram Doubler one though;
you might have to go messing with Ram Doubler resources or invisible
files to get at that one.

Errditor is on the usual Mac archives.

The "Welcome to Macintosh" message is stored in one of the STR or STR#
resources in the System file (if I remember correctly) .  Good luck
finding it though.  There are thousands.  I've kept a list of
miscellaneous strings I've run across in the past; but that one isn't in

"About This Macintosh..."
   Finder: STR ID 10000 ...and...

"Finishing Move..."
   Finder: STR# ID 8750, index# 16

"Clean Up Desktop" menu item
   Finder: STR# ID 10250, index# 1

Font Example Text (when you open a font in the Finder):
   Finder: STR# ID 14516, index# 1

"Starting Up..."

A better way is to install a custom picture screen.  You can use this to
replace the Mac O/S two-faced pict.  You can create a large PICT, you
should leave some space at the bottom for the loading status messages.
Then open up your System Update File with ResEdit or Resorcerer and paste
your PICT into resource -16506.  There's a few similar resources there for
black and white and 8 bit screens.  When you restart your machine, you'll
see your custom pict screen displayed.

I suspect you will have to do this conversion the hard way; i.e. extract
the mantissa, exponent and sign bit individually and use these to create a
"double" on the Mac. Use frexp() to apply the exponent to the mantissa.
Also, check the order of bytes in the mantissa; it is probably little
endian (least significant byte first).

To help with this, you might want to search the web for sources to XDR
(eXternal Data Representation) libraries, which are used to read and write
assorted binary C data types, including floats. It even supports VMS native
float format (different from IEEE). The code as described won't act as a
convertor, but will give you good examples of how to deal with endian changes.
XDR routines assume that they wrote the data out, so they swap endians et al
based on what their target neutral format is. You might luck out and find
that the PC standard format is the same as that expected by XDR.

The code was originally written by Sun Microsystems, but is generally
available in source form now.

 Ive been developing an app that really depends on the max

when doing beta testing I encountered color classics, screen resolution
being a max of 512 x 342.

 To rewrite the program to support the lower res would be a REAL pain,
so does anyone out there  know how common this is the max res?
If its any I've noted that the only four macs I can find that support my

in all other respects bar resolution are:
 Mac SE/30, MacClassic II, Color Classic, Color Classic II.

That isn't the only resolution you'll find smaller than 640 x 480. Apple
sold 12" color monitors for a while that are 600 x 400 or something like
that. When sales dried up they unloaded the monitors into schools. They
are the bane of all educational software developers, and only recently
have they been replaced in some schools with 13" monitors.

All of the PowerBooks prior to the 180c and the Duo 280 (I think that's
the model number) had LCD screens smaller than 640 x 480.

If you want your code to be compatible with all Mac you'll have to
support the lower resolutions.

The freeware utility database "Guru," available in the usual places, has
some good info. And Ziff-Davis used to publish a Mac models database but
I don't know how current it is. Apple dealers get little pocket booklets
and wall posters showing all of the Mac models and their specs. If you
can't get one from a dealer, call Apple at [phone] and ask for
one. When you have a question about Apple's sales figures or their specs
it's always best to first call them; I've never seen them answer that
kind of question in a Usenet group.

Couldn't you just copy the picture to an offscreen, get the user's rect
and then do another copybits using that rect inside a
OpenPicture()/ClosePicture() wrapper?

I think you need to look into the OpenPicture() and ClosePicture()
toolbox calls.  Check out IM Imaging W/ Quickdraw.

After getting the rectangle your user wants the picture cropped to, do an
OpenPicture (), followed by CopyBitsing that rectangle onto the same pixel
map. End by doing a ClosePicture (), and saving the resulting picture to a
file.

Yup.  Basically, there are two ways of doing this, depending if you want
to remain vector information, or just keep a bitmap of the selected area.
Here's the pseudocode for it (I'm in a lazy mood this morning):


draw original image in window
cropped image = open new color picture

if bitmap version

    copybits cropped area in place

or vectorial version

    draw original image
end

close picture

Close. DWRD is the equivalent of a C short integer. It will also be the
same as a C int if the compiler is set to use 2-byte ints, but the size
of an int is not defined to be any particular size. DLNG is equivalent
to a C long integer.

Use Resorcerer. It can change the data for you after you've entered it
if you have to change the template. And it has much better documentation
that ResEdit.

Symantec closed their Bedford Massachusets office a few months ago.
They renamed their development tools group to Internet Tools group
or something like that.  Some people moved to CA and last I heard they
were trying to hire for the group.

They have publicly stated they will continue with their C++ effort.
I have absolutley no confidence that they will do so nor do I have evidence
that they will. OTOH I do have evidence that they don't follow through.

For example I found and reported a probable bug in the C++ pre-processor
wrt nested macro expansions. I was assured that "....you will be kept in the loop....".
Hah.

Although their IDE has some pretty important and nice features that are not yet
in CodeWarrior, (multiple open projects, nested projects, a more mature compiler),
etc I expect CW will get there one day.

I also note the fall in the Symantec share price. Even their shareholders must be getting
nervous at the price drop.

Putting it all together I conclude they don't really care anymore.... not the engineers
of course but the giant brains running the oompany.

Just my personal opinion though.

I agree with Peter that Symantec has a definite history of not following
through, in all of their products on Wintel and Mac.

The important thing to remember, though, is that the Macintosh Java effort
is based on technology that came from the Bedford office, and the Java
teams are using the Symantec tools for their work. By necessity the core
tools will be maintained and enhanced, as required.

>For example I found and reported a probable bug in the C++ pre-processor

>Hah.

Well, you probably have. The problem is that there probably hasn't been any
news to inform you of. I reported a bug const bug in the compiler and was
told that I'd be kept in the loop too...

>I also note the fall in the Symantec share price. Even their shareholders
>must be getting nervous at the price drop.

If you think there is any relation between the stock price and Symantec C++
you are *very* mistaken. Symantec's stock went in the toilet months before
anything happened to Bedford, and it certainly was *not* related to C++.
Indeed, until Java the development tools portions of the company were a
flea on a large rat.

>Putting it all together I conclude they don't really care anymore.... not

I would posit that management, with a couple of exceptions, didn't care
*ever*. One of the reasons I left.

Symantec decided to reduce the price of Symantec C++ six or seven months
ago in an effort to make it more (financially) appealing for developers to
"give it a try".

It is true that Symantec is focusing on Java on both the Intel and
Macintosh platforms, though they are keeping a "core tools" group which is
focusing on the C/C++ compilers and environment. Work is continuing on the
IDE and releases are scheduled for the end of the year (last I heard).

       As I've mentioned before, Symantec seems to have a sort of
product cycle, like the auto industry.
They get a product working, promote it heavily, get sales up, and then
don't change it much for a few years.  Once sales slip seriously and the trade
magazines start saying bad things, they put some resources into the
product and do a major revision.  The Norton Utilities and the C/C++
tools have both been through this cycle about three times each.

Look at Develop Issue #13. Jim Luther wrote a definitive article
explaining asynch. completion routines for 68k. You need some
assembler glue :-( It's a mess. The article does _not mention PPC completion
procedures, however. They should be easier.

One good place to store your A5 is to place it in a structure after your
parameter block for your call in your calling routine. Then in your
completion routine, cast the pointer to the parameter block as one of your
structures. ( Which it must be, or it wouldn't be passed to your
completion routine. ) The odd thing about completion routines in C is that
you must retrieve the value in Register A0 and place it in a variable to
access your parameter block.This can be done by placing code to get A0 in
line with 68K machine code. If you need an example of this, e-mail me at
[e-mail] and I will dig something up. ( Hopefully, not someone's
mother ) ( Ha Ha )

There's a few different approaches (and probably an FAQ somewhere...):

1) Cross-platform API (e.g., Zinc/zApp/...)
   You write to a proprietary UI api, which is then implemented on
   multiple platforms. This may be a good way to go if you don't already
   have code written on a system-specific API. You may lose platform
   look&feel somewhat, and it will likely be slower than native.

2) Implement Mac & port to Windows.
   I know of at least one company that provides port of Mac toolbox
   on top of Windows API: Altura. They have a product called Mac2Win
   that works this way. This would be a good way to go if you already
   have a Mac product that you want to migrate to Windows without a
   complete rewrite.

3) (Converse) Implement Windows & port to Mac.
   Microsoft and Willows sell porting packages that implement the
   Windows API on Mac. If you already have Windows app (or expertise),
   this may be a good solution.

Interesting question.  I've been looking at a variety of alternatives
myself.  I won't repeat what Jeff has already said, but I would like to
add a few other possibilities to the mix:

    (1) Java
    (2) Python
    (3) TCL/Tk
    (4) Perl 5

I am no expert on any of these languages/environments, so I cannot comment

Here's a routine I wrote to build a table of all the files within a given
directory.
It differentiates between files and folders as well.

Code seems stable, but I haven't tested it thoroughly,it's good enough to
give you the idea.
Basically, you loop doing PBGetCatInfoSync giving it a incremented index

Hope this helps

Look for MoreFiles 1.4 it can be used to do what you want, although
that's not a built in function.

Get a copy of MoreFiles from

Some time ago I wrote an app for 68k Macs to emulate an Applix 1616
environment. Ok, since most of the world has never heard of the "Applix
1616", it was a 68000 based machine with a pre-emptive multitasking
environment rather like unix. I developed my Mac version to the point
where it understands most of the basic commands (ls, cd, etc) and can run
executables. GNU C runs under it, so you can port missing commands to it
if desired. The app ceased to work when I changed to a PPC, partly because
the PPC thread manager doesn't support pre-emptive threads, and partly
because the 68k emulator that comes with PPCs doesn't appear to emulate
TRAP instructions. Lemme know if you want the source.

I'm trying to output a short to a text file using the following line:

myError = FSWrite (fileRef, &count, &curNode->selected[i]);

where fileRef is the reference of the already opened file, count = 1L, and
curNode->selected[i] is a pointer to an array of shorts in a struct.

I know the value of selected[i] is valid, but when I open the output file
I always wind up with a null character. Any ideas what's wrong?

Better advice is to use sizeof(short) rather than hard-coding 2. A short
is two bytes on the Mac, but not everywhere. The size of a short integer
on every machine is sizeof(short).

Subject: displaying a pixmap on screen
Date: 1 Nov 1996 21:04:36 GMT
Organization: UCLA Division of Brain Mapping

I am trying to display a pixmap on a mac screen.  I can't get it to look
the way I want it to.  It is a 128x128 pixel 8-bit grayscale MRI image
which appears fine when I display it on NIH image but I cannot get it to
display on my program.  Does anyone have experience reading in raw data
files (not picts, tiffs or other preformatted files) and displaying them
on the screen?

I do not know if I need to convert the image to 48-bit RGB before
displaying or what.  If anyone can help me, please let me know.  I can
forward you my code and explain exactly where the problem is.

I am using Code Warrior 9 and program in C.

Thank you.

Hi Robert,

8-Bit color depth means, that a color lookup table is used.
You can display 256 different colors or grayscales at one time.
Every color( of the 256) has an index in the color lookup table
and a corresponding RGB value. Your picture is not using the
system color table. I gess that it has it's own.
This should be defined in the resouce "pltt" or"clut".
So you have to set the current color table with "SetPalette".

Bye Oliver

One approach is to create a GWorld with a depth of 8-bits. Attach a 256
entry grayscale color table to the GWorld. Load the GWorld Pixmap with
your grayscale image data (8 bits per pixel), then do a copybits to your
window.

If you don't attach a color table to the GWorld, the system uses a default
color table which will probably not give you the results you want. The
grayscale color table that you want probably runs from black (0,0,0) in
the 0th location and then linearly increases to white (65535,  65535,
65535) in the 255th location. The system grayscale color table (resource
ID = 40) runs in the opposite direction. If you use it, you will probably
get a negative of the image. In other words. you may have to make your own
grayscale color table. You can do that in ResEdit (it's a pain but can be
done).

Couldn't hey also use the system grayscale table, then call InvertRect()?
This would avoid having to create a color table in ResEdit, or by other
means.

Yes, that's right. According to Inside Mac, for indexed color, Quickdraw
performs the inversion on the pixel indexes of the color table when you
call InvertRect(). Seems like there's always several ways to something on
the Mac.

can anyone point me to some decent, detailed instructions on editting and

     Make a PICT by using any paint or image-editing program, save the
file as a .PICT, and use ResEdit to cut and paste the file's PICT resource
into your own.

Use any paint program and paint the picture.  Select it and copy it.  Go
the ResEdit and make a new pict  resource.  Open the blank resource and
paste in you picture.  Voila.

Editing PICT resources is not too complicated - even SimpleText can cut
and paste selections of a PICT resource. You might want to try working
with ClarisWorks Draw or some other application like that to actually
create and edit PICTs. ResEdit is useful if you want to change PICT
resources in applications (eg. change a spaceship picture in a game).
Usual disclaimers about ResEdit - don't use it unless you know what you're
doing.

You can mail me if you want some more specific info.

Cheers,
   Marcus
