Your programs are written to assume something to be true that is only in fact 
true on the MS/PC/DR-DOS operating systems.  Your programs, as they stand at 
any rate, have thus locked themselves into MS/PC/DR-DOS.  

Is it your intention to build DOS programs ?  I suspect that it is not.  Only 
when the target operating system is MS/PC/DR-DOS is it meaningful to make use 
of the macros "stdaux" and "stdprn" (analogous to the standard "stdin", 
"stdout", and "stderr" macros) in a program.  If you are intending to create 
OS/2 programs, then your applications need to be rewritten to stop assuming 
something that isn't actually true on OS/2.

 SN> All three programs compile flawlessly under Turbo-C 2.0, [...]

That's because Turbo C targets the DOS operating system and your programs are 
written for DOS.
