Frank,

You can run gempak on one machine and display the results back to another 
workstation.

To display your results to your remote X display, on your X86 host,
set the environmental variable DISPLAY to your remote machine, eg
setenv DISPLAY machine_name:0

(this is assuming you are running under a csh, and your remote machine
has an X server running on screen 0).

On your remote machine, you must allow the X86 host to connect to
its X server. Before trying to send a display back, on the remote machine
type:
xhost + server_machine

This xhost program tells the local X server to allow connections from
the server (X86) machine.

The xhost command is located under /usr/openwin/bin on Solaris platforms,
and under /usr/bin/X11 on many others, including OSF/1, SGI, AIX, etc.

The display which you are sending your gempak output to must be
running an 8 bit pseudocolor default visual.
