IPT in Palo Alto, CA offers a product called Fortran-Lint
which  we  use  on a Sparc station.  It is also available
for other DOS and Unix platforms.  Fortran-Lint is a very
good  global  source  code optimizer (we also use MAT and
Quibus's FORWARN; Fortran-lint  compares  favorably  with
both).

Among  its  vast  array  of  very   useful   diagnostics,
Fortran-lint  includes an apparently very rigorously com-
plete, if a bit conservative,  list  of  variables  which
_may_  be referenced before set.   If you SAVE these, you
should be ok.  (You may also catch a few real bugs!)
