I wish to port 250,000 lines of DEC Pascal code running on COMPAQ Alpha under OpenVMS/X-Windows to under Linux/X-Windows on Intel (and on Alpha if possible). I know that I will have some considerable problems with the non standard parts of DEC Pascal but GNU Pascal seems to be getting better all the time. The question I have is can I keep the same user interface, i.e. direct X-Windows and MOTIF calls from the Pascal code, i.e. is there an X-Windows/MOTIF binding for GNU Pascal. If the answer to this is yes please tell me. If it is not please tell me how GNU Pascal programmers develop GUI's.
