This may be obsolete information, but I dealt with DEC in trying to get sample PHIGS code for their VAXstation 3520 about a year and a half ago. At that time I got executable code, but no source code and was told it was written at the "PEX library" level and not with PHIGS because their PHIGS library was not yet available. However, they planned (at that time at least) to support no API to PEX other than PHIGS and therefore they did not want to give out any code that was written at the "PEX library" level. I don't know, but I thought this might have been what the original poster meant when he said "PEX" programs.
