Don't forget to :RESET these file equations after running the program
a *lot* of programs (like anything written in PASCAL) use "INPUT" and
"OUTPUT" as the formal filenames associated either with FOPENs to
$STDLIST/$STDIN or as files to process.

Leaving a :FILE OUTPUT= lying around is a good way to A) wipe out the
file it points to, and B) confuse the heck out of yourself as to why
a lot of programs either won't run or produce no output.
