This particular question seems to come up on a regular basis.  I wonder
if it is in the FAQ.  Anyway, I recall using a tool called AdaQuest by
General Research Corporation out of Santa Barbara, CA.  The last contacts
I had were Chuck Hobin (Staff Scientist) and Thomas Strelich (S/W Engr
Ops); voice phone (805) 964-7724.  There were two versions of this tool,
one running under VMS and the other under DEC/Ultrix (perhaps retargeted
to generic Unix workstation?).  However, the tool worked somewhat
differently and gave somewhat different results between the two
versions.  It basically walks DIANA trees to satisfy user queries.  Since
VADS keeps its DIANA code around, the UNIX version just ran off existing
Ada libraries, meaning that you had to have compiled your code already.
Since DEC Ada doesn't keep DIANA code around, the VAX/VMS version comes
with a preprocessor to create it.  This means the VMS version is
"slower", consumes lots more disk space, and has some incompatabilities
with the DEC Ada interpretation of legal Ada code (since the front end
was actually the Intermetrics front end repackaged for VMS, a la Byron.)
I believe the only problem has to do with what operators associated with
a generic actual type parameter are visible at the point of an
instantiation. Unfortunately, I believe only the VMS version has a 
Set/Use report.

That's the long answer.  For a short answer, I would check the DEC VAX
tool SCA (Source Code Analyzer).  Its built to interface with the VAX
Ada compiler, and I believe can generate a Set/Use report.  

Comments, anyone from DEC or GRC? (Or Sun, or Verdix [oops, Rational]
for that matter?)
