It sounds as though your program isn't as standard f77 as you think it
is, if you have 2 f77 compilers which can't even compile it. At this
point, all bets are off. If I had a program which 2 different compilers
couldn't compile, I'd suspect a bug in my program, not the reliability
of a 3rd compiler. What error messages do you get from the 2 compilers
which reject the code?
If that doesn't help. I suggest you turn all the checking options on all
of your compilers on and start fixing any errors they report. Strong
candidates include a reference to an array element outside the bounds of
the array and using a variable which has never been initialised.
HTH,
Catherine.
