As far as I know (at least I am pretty sure of what I say for Sun-3's
and Ultrix, so I don't see why this would be different on Sun-4's),
you *have* to resort to features outside of Pascal to test file
existence.  To reduce your grief, all I can say is that it is very
easy to call from Pascal the routines in the C library, including
"access" which would fit your needs.  If you're interested I can post
a few lines of code doing the job.
