If it is truly Fortran77 code with only a minimum of more modern
features, the utility FTNCHEK may be useful. It can be persuaded to
produce a call-tree, for example. Of course in any actual run not all
of your procedures may get to be called, depending on the logic of the
code, but there is no way to examine the code statically to determine
this. Running using prof/gprof is a way of finding what is actually
being invoked.
