To perform comprehensive analysis of Fortran based systems, I'd
suggest using the INDEX program from the VAX SIG tapes (DECUS).
It does about every imaginable static analysis job (even will draw
flowcharts...) and is free and in source. Updates have appeared regularly
on the VAX SIG tapes for some time, though I think the most recent may
be spring '86. Generally speaking, trying to run a VAX system without
having a complete collection of the DECUS VAX and RSX SIG tapes is
like trying to run with your legs tied together. A decent VAX programming
environment will often have half its tools from DECUS sources. It's a
huge library and a VAX system manager should be aware what's there, just
because it'll save so much time (and money). If you need to do static
analysis of things like Algol, you probably have to pay someone... but
if you want static analysis tools for languages like Fortran or Ada,
have a look at DECUS. (To a degree, this is true for C too...).

p.s. The old Amsterdam DECUS tape and Hamburg DECUS tape from the
early 80's had another VERY nice Fortran static analyzer. They are
in the DECUS Library catalogs but have lousy abstracts that won't
tell you much of what's there. But they, like other symposium tapes,
are worthwhile and even though they are marked RSX tapes, they have
much that runs native mode and is useful on VMS systems even without
the VAX/RSX product.
