some code from that time that would compile "back in the day",but
that same exact piece of code will NOT compile on vms 7.x with the
compaq compiler. It's almost like I need to have a system running vms
4.2 with the fortran of the time to get it to work.
I'm sorry if this is a stupid question, but have you investigated
compatibility-related command line options for the F77 compiler?
I have to assume
the resulting binary would work on modern systems? I have some
classic game source code from the time I want to get back online and
in the archives
Cross-release binary compatibility is generally pretty good in VMS;
I'd say it's worth a try. For that matter, I'd expect the old compilers
themselves to run as well.
