While I cannot help with VisualBasic, you can find a Java example
doing exactly this at the URL below. The data between HP 3000 and PC
(or whatever Java client platform) travels across a regular telnet
connection; from the HP 3000 program point of view it's plain $STDIN
and $STDLIST.

The program on the 3000 side can be QUERY (or better QUERYNM) or any
other (custom) program that has a line mode "prompt & response" style
user interface.

I wonder, whether it would be fun to use the same approach to create a
little "MPE Desktop" GUI with pulldown menus or pushbuttons for tasks
like SHOWJOB, DISCFREE, etc. Unfortunately this little excercise would
most probably consume too much of my sparse spare time.

;-) Lars.
