for a fortran program. What kind of error is that?
What might be the cause of it? I've been stuck on this
for two weeks and now I am devastated.
Any suggestion will be highly appreciated!! THANKS!!!

divided by zero, inexact, overflow, underflow, invalid
If you want your code to run continuously without exiting
for this error, your compiler should have one option for
that, for Sun f77, it is the default.
With deguggers like dbx, you will find the exact location
of such error in your code and you will be able to see values
of some varialbes in stack.
Good luck,
