This is not a bug. The FORTRAN standard does not require that a common
block that is first initialized in a subroutine be saved after the
subroutine is exited; although, most FORTRAN implementations do save it.
(Sorry, I can't quote the Standard but you can
see, for instance, Michael Metcalf's Effective Fortran 77, page 83.)
If you would like to keep the common block around and don't want
to clutter up the main program by declaring it there use the save
command:
subroutine foo(args)
real args,stuff
common/bar/stuff
SAVE /bar/
.
.
.
This should work (at least it does in compiler version 2.2).
(It sure is nice to finally see some discussion on a
real programming language in this newsgroup :-)

Shanghai is to Mai Jong is what Old Maid is to Poker.
Or in other words, it's totally different except for the fact that they both
use the same images on the tiles.

Bammi recently put GCC 1.36 on his server -- say "gcc -v" to find out
what version you're using.

When you say "executable size" do you mean the size of the PRG file?
That's not a good indication. There can be any amount of information
in the PRG file besides the program: symbol tables, debugging
information, etc. If you use -g on the GCC command line, that's your
answer: it generates LOTS of info for the symbolic debugger GDB (and
UN*X's dbx).
The right way to find out executable size is to dump the program's header
and look at the size fields. The dump will look like this:
60 1a tt tt tt tt dd dd dd dd bb bb bb bb ...
601a is a magic number. tttttttt is the text (program) size in bytes.
dddddddd is the data segment size in bytes. bbbbbbbb is BSS. Compare
the SUM of text + data, because GCC might be putting strings in the
text segment, while Megamax might put them in the data segment. Also
make sure they're both talking about the same things: use -mshort for
your comparison (even if the program doesn't work that way) if Megamax
has 16-bit INTs.
Of course, MegaMax C has *8* bit shorts, and some required keyword
concerning modules or overlays or something, so I have no respect for
it at all...

Just wondering, before I take the time to download this file, can someone
out there post a generalization of just what the Modula-2 Algebra system does?
Thanks in advance!

Subject: Prodigy run under Spectre GCR?
Message-ID: <24790@cup.portal.com>
HOward C. Johnson asked if anyone had gotten the Prodigy software for the
Mac to run under Spectre emulation...
A friend of mine investigated this very question, and found that the
Prodigy software, which ran perfectly on a real Mac, wouldn't run on
his Spectre. I don't know exactly what the problem was, but my friend was
quite disappointed. We've both used the IBM version of Prodigy under the
pc-ditto emulator, and while it runs, it's far too slow to be useful..
we'd looked forward to the Mac version since Spectre runs Mac software at
full speed (or better). Unfortunately, it seems destined not to be...

Message-ID: <1989Dec7.080555.3093@uwasa.fi>
Do anyone know where I can ftp a PD program called
rattrap, which should allow me to use menus like in
the Mac (ie. so that they don't drop so easily).
If not ftp perhaps someone can mail it to me.

Message-ID: <24788@cup.portal.com>
Pit Capitain, the author of the ALADIN Mac emulator has replied to a lot
of the questions and comments about his offer to release the ALADIN
emulator as shareware...
One thing I've been wondering about though, is how exactly was the ALADIN
implemented..? Obviously it's a disk based, software emulator.. but,
how was the problem of needing Mac ROMs addressed..?
Was a cartridge similar to the Magic Sac offered to hold the ROMs..? Were
you required to figure out something on your own to hold the ROMs..?
What exactly was a running configuration of ALADIN like..?

Good news....!
The STacey has passed its FCC type acceptance testing as of today...
according to Atari, it should be in the stores in 30 days or less.

[...]
I'm not way off base. I may be wrong in your case, and in fact I may be
wrong in the case of every person who reads comp.sys.atari.st! But
active members of online communities aren not by any means
representative samples of ST owners. If the online community were more
ubiquitous, I would grant that your experiences were representative,
but it isn't, so I can't. My opinion is based on my experience working
in a computer store, working with user groups, supporting development
tools, and talking with Atari's user group and developer support people.
Users, by and large, want to use their computers.
As far as supporting hobbyist programmers, I take a pragmatic stance.
How much PD software comes from where is not directly important to a
computer maker. It is certainly indirectly important, because a wide
variety of PD tools make a computer a lot more attractive to the
informed buyer. But a wide variety of professional products make a
computer more attractive to the market at large. A lot of people buy
the computer that runs the software that they want to run. That is why
it is vital for computer makers to have a broad commercial software
base for their machines. In order for that to happen, strong support
for the companies that produce that software must exist.
A side effect of having strong support for professional programmers is
that end users get supported as well. More books get written by the
professionals, making more information available to the hobbyist than
the computer maker can hope to provide. A broader base of technically
competent people exist to answer the questions of hobbyist programmers.
All these programmers will be happy because they can get their
questions answered and they can solve their problems without having to
stumble around in the dark too much.
| BESIDES, aren't I (an end-user who uses
| his ST to write programs for enjoyment) a valued customer????
| Aren't my CUSTOMER needs important??? Your attitude really bothers me.
Every customer is a valued customer. You are an espeically valued
customer, because you take the time to give feedback on how you think
Atari is doing. I'm sorry that my attitude bothers you, but I think
that it's a practical one. I hope that I've clarified where I'm coming
from.
Please note: the opinions expressed in this article are mine and mine
alone. Atari has its own.

Subject: The Relevance of the PD FORM docs to the PD distribution of FORM
Message-ID: <581@nikhefh.nikhef.nl>
Concerning the remark about `missing features' in FORM.
The manual of FORM describes the entire FORM 1.0.
The remark about the missing features concerns future
development. A symbolic manipulation program is never realy
finished. You have to stop somewhere and say: 'this is version 1.0'.
Then in later versions there will be more features.
The program as it is distributed is fully self sufficient and
can be used for a very large number of problems.
Suggestions for more features will be very welcome.
