Hello,

I develloped an interface code which allows me to access and use
the C language functions of PHIGS through LISP. 

There seems to be a small problem, though: I have a program in C
that works perfectly well that I "translated" in LISP, but the
latter gets stuck whenever I use psetviewrep3 in which case it 
gives me an error message saying:


%PHIGS-E-ERROR_152, Invalid viewport: one or more of the minimum limits 
Exceeds its corresponding maximum limit in routine psetviewrep3


I checked for the viewport values and they get set to the ones given in
the C program correctly. 

Any help is appreciated.

Thanks in advance,
George S. Kardaras
