We've ported quite a lot of DEC Pascal to GPC without major problems. Certainly GPC2.1 hasn't given us problems with segfaults or internal errors on both i386 or Alpha platforms. We have had to do quite a lot of manual code conversions though. Areas which spring to mind that needed changing in our code was:
GPC doesn't read enumerated types from files; GPC doesn't support the :=ZERO assignment; GPC doesn't use file i/o and read qualifiers, especially ERROR:= CONTINUE; VARYING [] OF CHAR must be replaced by STRING(); REAL is best defined as SINGLE; VMS runtime library functions aren't available (obviously!). I can't do key detection as I do under VMS INHERIT and ENVIRONMENT become INTERFACE/IMPLEMENTATION and USES Remove [GLOBAL] and [EXTERNAL] [STATIC] becomes static No D+0 etc. for double precision exponents The only compiler bug - global string definitions in modules don't always work yet (I don't think?)
I have code examples of how I've worked around the enumerated type reading and ZERO issues if you wish.
I'd like to this is if you're willing. I'm trying to port my old Ph.D. project (for old times sake I suspect!)
