Hey, Whats wrong with CCP pgms ? They actually work very similar to CGI
pgms. I could probably drag some old pgms off of tape and reuse them. Smile

"I have no idea how they do screen I/O using RPG on the mainframe."

Made me think back (shudder!! chills up the spine!!) to the old System 3
days and CCP. What fun add a new interactive program and then have to
re-generate the assignment set(?) so when you restarted the interactive
partition (see the i5 ain't got nuttin, I remember multiple partitions on
the System/3) it could use the "new" program................

great, now i get to go abck to the therapist
