Dear comp.lang.pascal.misc,

I recently found a printout of a Pascal program -- a parser and


hopes that it might help, the first few lines go...

{$O calculator}
{$S+ segmentation on }
{$I- no io-checking }
{$R+ range checking }
{$D+ include debug symbols}

USES
PasPrinter, MemTypes, SANE, QuickDraw, OSintf, ToolIntf, MacPrint;

I've scanned it into a file, done as many corrections as I can
find, but there are still many little typos from the scanning. I want
to get the program working again on Windows NT, preferably as Pascal,
otherwise hand-porting it to another language.

What are the possibilities on NT?

With kind regards, Sandy --

Should be easier to run it on Pascal than change it to another language.

The "modula style units" you show above are also common to UCSD, Borland
and deriviatives.

Try Freepascal, has the Apple/UCSD Pascal units concept via the Borland heritage
and, as the name says is free! Runs fine on Linux and Windows.
Ofcourse the Mac specific units have no equivalents,

Wouldn't it be easier and more appropriate just to re-write the thing
from scratch?

programming in 1991, as such you should by now have a better
understanding of programming and all the related concepts such that
you'll be able to write a better whatever it was you wanted to get
running.

Do you build a new house for yourself when you find a plumbing problem ?

GPC should run on NT and should handle well classic or USCD Pascal.

Is the example in USCD Pascal then? As a student back then, '91, I
can't remember. What does GPC stand for in full? GNU (hopefully!)
Pascal Compiler? Gdansk Pascal Compiler?

I assume it is in Apple Pascal which can trace its roots back to UCSD.

Correct. See <http://www.gnu-pascal.de/gpc/h-index.html>. We use GPC
(but under Linux) and are very happy with it.

I guess it depends on the extent of the plumbing problem. If OTOH there was
a serious problem with the foundations I would rebuild or (more likely)
move.

Back on the topic of programming though, I've just completed a Pascal to
Oberon translator to help me make such moves.

Apple started with USCD Pascal but than evolved its own features. Only
looking at the whole program one can tell if it is more like USCD or
modern Mac Pascal (and no, I am not volunteering to examine the program
for you). What I am telling you is that gpc supports some features
from classic and USCD Pascal which are present in Mac Pascal but absent
in some other compilers. I do not know if your program uses such features,
but you asked for options so I give you one.

The program clearily wants to use Mac specific units and that is IMHO your biggest problem.
