Peter,

As an alternative, you might investigate installing the IRIS Remote Graphic
Library (available from your friendly purveyor of IRISes) on your VAX.

This will permit you to write your graphic display code using
familiar IRIS graphic calls in FORTRAN or C on the VAX, link this to your
application code, and run it on the VAX.

As you generate graphics information, it is sent to the IRIS which is running
a terminal emulation program (thus becoming a fancy terminal to the VAX).

We have linked a MicroVaxII running ULTRIX to our IRIS this way on a
TCP/IP LAN. It has the advantage of eliminating the need to build a
graphic data output file, the data transfer step, and the need for a
separate graphics display program to be written on the IRIS. A
disadvantage is that your graphics display speed will be paced by the
VAX, which may or not be a problem in your application. I know the RGL
is available for VMS systems, but am not sure about XNS network
support, though this is easily checked by a call to your friendly
supplier.
