If DISPLAY wasn't set, then you might see a NODEVC -83 error. You might
also hand the gplt process which tries to spawn the xw, gf, or ps driver, so 
make sure
all your gplts are killed, and your message queues are clean.

If you still have trouble, you might try sending the DISPLAY to another machine
that you know works so that you can rule out simple X server problems
instead of GEMPAK code incompatibilities.

Good Luck,

Steve
