Help.  I hate it when you are in med rez and you cannot run a low
rez program without setting the preferences.  Is there a way, like a
program, to switch the rez automatically for you. I have seen how
Spectrum 512 will change the resolution so it seems like it would be
possible.

This was a problem at first, as I am a beginning ST programmer and
am not a registered developer (yet..  :-).  Of course, the people
who wrote the MWC documentation didn't bother mentioning the
fact that the memory has to be ALIGNED..  But they provided a nice
example, in which they aligned the memory, so that's how I learned..

Kind of interesting, that the example in the MWC manual does have
32K hard wired in.  Of course, it's only an example, but for someone
learning how to do something for a first time, it's not setting a
GOOD example..  sigh..  (at least it does have LOTS of examples)..

Thanks!

NO! What you describe is g++, GNU's version of C++, and not gcc.
gcc is an ANSI compatible C compiler. The Atari version of g++ is
available, but still somewhat buggy, I hear. The Atari gcc is (I hope)
no more buggy than the other gcc's, which is to say it has a few bugs,
but probably no more than commercial compilers.

Well, they're all just compilers. But they all support different features.
There are two standards for C; K&R first edition (the original book by
Kernighan and Ritchie) and ANSI C, which is the new standard (and which
is covered in the second edition of Kernighan and Ritchie). All of the
compilers you mention are more or less compliant with K&R 1st edition,
and they all have (different) extensions to it. The GCC also complies
with the ANSI standard (and has extensions to *that* as well!).

I've used Laser, Sozobon, and the GCC. I only use the GCC now; I find the
other compilers quite limiting in the features available. On the other
hand, the GCC pretty much requires a hard disk and 2 megabytes of memory.
If you don't have this much, you might consider one of the alternatives.
Sozobon is a pretty decent compiler, and the price is certainly right.
And the commercial compilers do have the advantage of better documentation
and (often) nice graphics shells, if you care about that.

You gave up two keystrokes too quickly. Try "cc hello.c".

If cc sees a filename with no .ext, or with .a, or with .lib, it thinks
it's a library. You said "cc hello" and cc looked for a library named
hello. It didn't find one.

Yeach, the raw, unoptimized output from hcc looks pretty bizarre. :-)

This one has me stumped; I "jas source.s" all the time without any trouble.
If jas is getting a filename, it should assemble it.

As Bill Powers <[e-mail]> pointed out, Pcommand may be
the culprit. It does some goofy things. Try gulam.

This, of course, is the primary purpose of make. By causing budding
programmers to smash monitors and hang themselves, the supply of
programmers is restricted, and salaries can be kept high.

Seriously, using make to maintain a program with fewer than half a dozen
source files is just a pain in the gazoo. Forget about make until you've
got C under control.

Sozobon C expects that paths will NOT end in a backslash.

The source code for cc indicates these default search paths:

/*
 * Default paths for executables and libraries
 *
 * Always check the root of the current drive first.
 */
#define DEFPATH         "\\bin,\\sozobon\\bin"
#define DEFLIB          "\\lib,\\sozobon\\lib"
#define DEFTMP          ""

... so if the programs and libraries are on the current drive, you usually
don't have to define the environment variables. I often compile on D:
while the Sozobon directories are on C:, so I have set up:
PATH=.,\bin,c:\bin
INCLUDE=c:\sozobon\include
LIB=c:\sozobon\lib

Subject: Monitor, music and spreadsheets

Dear Gang,

I tried to post this once before, but the Janet->Usenet link seems a bit
iffy these days, so I'm not sure if it got through. I never got a digest
containing it at any rate....

1) I have an SM124 which seems to be slightly out of focus. I don't want to
send it back because it's a replacement for a completely duff one (it's only
two weeks old, by the way) so I thought I'd ask if anyone knows what to tweak
inside top adjust beam focus.

2) I need a music printing program. Input - qwerty, output HPLJ+/HPGL/spooled
PostScript. Piano music with included text if possible. Output should be of
publishable standard. It doesn't have to drive a Yamaha 600 Turbo synthesiser
or anything else fancy, just print music. Something like Music, the Troff
preprocessor. (Are there PD versions of pic and troff for the ST?). Any advice
appreciated. Replies by email, please, and I'll summarize back.

3) Summary of advice I was given on spreadsheets. Unanimous -

                BUY LDW POWER.  Simple, eh?

Well, that's all folks. Awaiting replies with baited breath.

Needless to say, it's extremely rude to call some people pirates
because they rent software. Libraries rent books, video stores rent
movies. Video stores rent Nintendo carts, which contain software.

In short -- piracy is an issue you deal with by educating users, not
by insulting legitimate businesses.

Btw, gcc is not a C++ compiler. g++ is a C++ compiler. gcc's feature is
that it's ANSI C.
