Here's our situation:  We've received a lot of FORTRAN 77 code from
another group of people.  This code wasn't exactly written for portability.

Among other(!) problems, some variables in some of these routines expect to
retain their values from invocation to invocation.  This, of course, is not
guaranteed (except maybe on certain systems).

We'd like to find out if anybody knows of a program that will process
FORTRAN 77 code and determine if any of the variables in a given subroutine
should be SAVEd.  (We could do this by hand, but there's a lot of code
involved, and some of those subroutines are BIG!)

So, to avoid (if possible) having to write something like this ourselves,
we'd like to know if this has already been done.  (Who wants to reinvent the
wheel, anyway?)  We'd prefer public domain/shareware/etc., but ...

Adv(Thanks)anc for any info/help/pointers/etc.

Chris

P.S.  We're currently using VAX/VMS and SUN/UNIX OS's.
