(I find that I cannot reach @motcid.uucp from my site, so I am
posting here.)

Unfortunately, it is much easier to _get_ the value of environment
variables in Turbo Pascal than it is to _set_ them. You will find a
set of PD units from TurboPower Software available as

PD1:<MSDOS.TURBOPAS>BONUS507.ARC,1,150435,8,900205,
  "Misc. TP 4/5 utilities/pgms from TurboPower"

on Simtel and mirrors. It contains a unit called TPENV which
provides many capabilities relating to environment variables. I'd
suggest you download it and go from there. If you can't get the
entire file, I can email you an excerpt I made specially for net
postings, but you would do well to grab the entire thing. (NOTE:
it appears that you'll have to give me a Bitnet-accessible address
if I am to email you.)

It is _real_ PD stuff, and although it is written to accompany
TurboPower's commercial library, it is easy to use on its own.

Cheers--                        --Karl
