This is a misunderstanding: DJGPP programs don't display the exit code
upon termination.  You are probably using RHIDE and running your
programs from within the editor.  RHIDE indeed displays the exit code
of the programs it runs (as do several other programmer's editors).

Probably because your `main' function either wasn't declared as 
"int main", or because it didn't bother to return a specific value
with a "return" statement.  In that case, its exit code will have a
random value.  Using -Wall switch while compiling would cause the
compiler emit diagnostics for these gotchas.

See section 22.24 of the DJGPP FAQ list, for more info about declaring
`main'.

There's nothing special about the codes, they are not generated by
DJGPP.  It is up to your programs to assign meaning to the exit code
and return the correct values from the `main' function.  DJGPP itself
has nothing to do with that.
