it's running :-)

According to Andreas Bauer:

DJGPP (including GPC) searches for libraries and such things in a 
specific directory structure.  Normally, an environment variable
points to the DJGPP directory, e.g. "H:\DJGPP", where there is a
configuration file for the rest of the story.  If you set it up
in another directory tree structure, you have to specify library
pathes either manually (-L) or by another environment variable
which should be in the DJGPP documentation.

Yes:  gpc foo.pas -o foo.exe 2>foo.err

Errors go to the "error device", therefore ">foo.err" is not sufficient.

I have the same problem.  Look into the GNU C documentation, section
"Extensions to ASM" or similar.  There is a description, but I had
problems to understand it.  Anybody out there who could explain
to both of us how to use that inline assembler syntax?

I think you *must* use assembly language.  Interrupts and such things
are not in Pascal's language standard.  However it would be nice to have
a Unit with a function (written in assembler) which solves this task ...

I don't know of such a thing.  There could be some hints in the DJGPP
and/or EMX documentation.

I don't know why the stack is used, and I will change it (and use the
data segment instead) unless somebody can tell me why the stack is 
preferable for the main program.

However, if you put the array into a Unit (or Module), it will be accepted.
