The Comp.Sys.Mac.Programmer Digest is moderated by Michael A. Kelly.

The digest is a collection of article threads from the internet newsgroup
comp.sys.mac.programmer.  It is designed for people who read c.s.m.p. 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.  You can post articles to any newsgroup by
mailing your article to [e-mail].  So, to post an
article to comp.sys.mac.programmer, you mail it to
[e-mail].  Note the '-' instead of '.'
in the newsgroup name.

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
cs.uoregon.edu).  Article threads are not added to the digest until the last
article added to the thread is at least one month 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 entire digest is available for anonymous ftp from ftp.cs.uoregon.edu
[128.223.8.8] in the directory /pub/mac/csmp-digest.  Be sure to read the
file /pub/mac/csmp-digest/README before downloading any files.  The most
recent issues are available from sumex-aim.stanford.edu [36.44.0.6] in the
directory /info-mac/digest/csmp.  If you don't have ftp capability, the sumex
archive has a mail server; send a message with the text '$MACarch help' (no
quotes) to [e-mail] for more information.

The digest is also available via email.  Just send a note saying that you
want to be on the digest mailing list to [e-mail], and you will
automatically receive each new issue as it is created.  Sorry, back issues
are not available through the mailing list.

Send administrative mail to [e-mail].

Supplemental Gestalt Selector Codes List *

Last updated: Oct., 21 1992 19:40 CET

Supplemental to the selectors listed in the Gestalt Chapter of
Inside Macintosh VI (IM VI), that is.
These can include selectors added by Apple's (system) software or
by software from third parties (your software?).
If a selector code is added by Apple software the entry also
includes if it is an addition to or not listed in IM VI.

I don't have all the documentation or knowledge and I don't want to.
I would like to see this list as a combined effort by different
persons who have together access to a wide area of information.
This list may contain (educated) guesses and perhaps even false
information, so no guarantee is made about the contents.
When there is a reference to a source you may expect there is a
higher probability it is correct.
If you wish to give me more information or correct the information
in this list, please mail me at [e-mail]

If you read this list in a Usenet group: you can also read it by
using finger to the same address.
    Tip: finger [e-mail] | more
My .plan file which you see when you do this is more up-to-date. I
will post this list to comp.sys.mac.programmer once a month. Or
when (a lot of) information is added/corrected.

In article <[e-mail]>, [e-mail] (Rene G.A. Ros)
lists a whole bunch of undocumented Gestalt selector codes.

Interesting. I shall be saving that list. However, you haven't included the
'tabl' selector, which returns the address of the Gestalt selector table
itself. This is what Carl Hewitt's GestaltDA uses to produce its list of
selectors.

Hi,

anybody there, having experince with executing code-resources ?


My problem:

I want to generate a ResourceFile with a code-resource in it
(from C, for example with Think-C), in order to open and exe-
cute it from and within another program.

I could'nt find any Information on it in 'Macintosh-Inside'
and got my only information from the 'Macintosh Technical Note'
#256:Stand-Alone Code (July'92). There's an example of using
resource type 'XCMD' (used by HyperCard) under PASCAL, but all
my trying to program this in C failed.

So, please please is there anybody who can help me, having
experince with it and/or can tell me where I have to look and
what I have to read for further information ?

Thanx in advance

I ask this very same question a while back . . . and now its my turn to
answer :-)

Basically you just load it, cast it, then use it.  Oh, of course, you have
first got to write it.  Let's say you are writing a mathmatical function that
get's two double's passed and returns one value.  You would then write then
code for the code-resource in the form:

double main(double x, double y)
{
    .
    .
    .
}

Once you've got it written, you need to include libraries.  If you use ANSI,
use the ANSI-A4 library (has to do with addressing schemes I don't fully
understand), and compile it all as a CODE resource (see THICK C manual).

Then to use it in a program:

main()
{
    double        (**myFuncHandle)(double x, double y);
    double        xx,yy,z;
    .
    .
    .
    myFuncHandle = GetResource('PROC',128);  //resource type and number arbitary
    HLock(myFuncHandle);
    .
    .
    .
    z = (*myFuncHandle)(xx,yy);
    .
    .
    .
    HUnlock(myFuncHandle);
    ReleaseResource(myFuncHandle);
}

Oh, I forgot to say, if you are writing a math type code resource, you'll
have to recompile ANSI-A4 so that it includes the math files from ANSI.
Currently, it doesn't (at least mine didn't).

I've been looking for info on the 'sysz' resource. IM or the technotes
don't seem to contain any info on how or when to use the sysz resource.
If I'm right, the resource contains a longword which "reserves" an
amount of memory in the system heap for my init. But do I need to use
a sysz if my init only uses e.g. 3Kb of RAM ?
Could anybody end my quest and point me to valid info on the sysz resource ?
I'd like to know everything there is to know about this resource.

That's all there is.  You should always include a sysz resource in case you
are approaching the end of the system heap space.  The System checks the
free space in the heap and compares that to the sysz amount and if the heap
is smaller then it grows the heap so that there is enough room.  I believe
that the System is free to grow the heap any amount it feels like, so there
should always be more room than your sysz requests.

You don't need one, because in a 3K INIT you are less likely to run into a
situation where the System heap doesn't have at least 3K available, but you
_should_ have one.  Just in case.

  Currently, the startup code guarantees 24K of heap space (not necessarily
contiguous) for INITs.  (I think it used to be 16K on older systems.)  If
you need less than that, you don't need to include a 'sysz' resource.  If
you need more, include a 'sysz' 0 resource.  Keep in mind that this is
memory available to your INIT at the time your INIT is loaded, and may not
necessarily be around later on down the road.

Selecting an item numbered higher than 31 causes this. It will be corrected
in an future system software release.

The usual practice is to use your creator.  As it says in Inside Mac VI,
page 3-42, "If you have registered a creator string with Apple, you are
strongly encouraged to use that sequence as your selector code."  If
everyone follows this rule, we won't have any conflicts.  For extra
safety, register an extremely obscure creator code and use it as your
selector.

Sorry 'bout that.  So many creator/file type requests come in that they
more or less have to be handled by someone running on autopilot.

Gestalt selectors are not registered by Apple.  A reasonable convention
is to use your creator type for your selector. If you need more than
one, pick something obscure, like a code with option characters in
it.  Be sure to include an upper case character since Apple generally
reserves codes without upper case characters in them.

Gestalt really isn't intended to be used for sharing memory blocks....

all deal with it, and you can find it on unix systems.

You can find Paul Dubois' rtf2other converter, his new
troff2rtf converter, plus various rtf docs including one from Microsoft
specifying the format:  anon. ftp to ftp.primate.wisc.edu, look in

I, too, think RTF is pretty cool.  And I'll make a prediction for you:
in the future, FAXes will be digital and by RTF.  No more stinkin'

RTF may or may not be a public domain kind of thing--from what I know about
the Microsoft people, they'll probably haul all of our asses into court for
deigning to mention the letters "RTF" without citing the trademark.

On the other hand, their lawyers could have been sleeping one day and
let the engineers do something nice for the computer world.  You'll
have to ask them.  And let us all know--from home or jail--if there's
some sort of copyright on RTF-style formats.

I'm having trouble figuring out how they could stop you from
reverse-engineering the format, but then I'm not a lawyer, am I?

Subject: Changing open resource files
From: [e-mail] (Greg Ewing)
Date: Wed, 21 Oct 1992 04:25:47 GMT
Organization: University of Canterbury, Christchurch, New Zealand

I'm writing an application that creates and edits resources for use by
another application (not written by me). Rather than stuff the resources
into the application itself, which seems a kludgy thing to do, I'm
putting them in a separate file and opening it with Suitcase.

The problem is that to test the created resources requires going
through an elaborate save/open file with suitcase/launch application/
try it out/quit application/close file in suitcase/open file with editor
loop, which becomes very tedious!

So, I'm wondering whether I can change the resource file while Suitcase
has it open. Attempts at doing this so far have had results ranging from
apparent success, through various combinations of Suitcase/my editor
being unable to open the file because it's busy, to system crashes.

Is there any safe way of doing it? If I test whether the resource
file is already open, and don't close it afterwards if it was,
I could at least avoid closing the resource file out from under
Suitcase (which seemed to be one source of problems).

Would that be sufficient? If so, how do I test whether a resource
file is open? There doesn't seem to be any obvious way of doing
this, although ResEdit seems to manage it somehow. ResEdit also seems
to be able to edit open System files, albeit with a danger warning,
suggesting that with care it is possible to do what I want.

Any help appreciated,

I've never actually used Suitcase, but I gather it opens those resource
files and puts them *behind* the System file in the resource map chain, to
make those resources look like they're in the system file.

If my understanding of how Suitcase works is correct, then you should be able
to do what you want to do.

Funnily enough, there was a discussion about this in this newsgroup just a
few weeks ago. The basic technique is quite simple: check the value of
the TopMapHndl low-memory global before and after opening the resource file.
If it changes, then a new resource map has been added to the chain, which
means the resource file wasn't previously open. If it doesn't change, you've
just reopened a previously-open resource file.

One does not design a human interface based on the fact that 3-D interfaces
look "real cool". One only has to sit in virtually any of the "real cool"
chairs built in the last fifty years by leading Bauhaus designers to understand
why: what looks "real cool" can often be acutely painful to use. First, the
interface should communicate; only then should it look "real cool".
