Thanks Barbara! That's helpful. We have not thought to vary off/on the
display device, since the user continues working on other applications
after getting this error. In terms of recovering from the error, I've
passed on the suggestion to close and reopen the display file when the
error occurs.

Sorry, I don't know whether splitting the EXFMT into WRITE and READ
might help. RPG just asks the system to do the operation(s), and handles
any resulting exceptions. My guess is that it wouldn't help. but in this
case, your guess is as good as mine.

The "Application Display Programming" manual has more information about
the minor codes.

For 80C0, it says
"Description: An error that is not recoverable has occurred on the
display device.

Action: Your display devices may need to be varied off and then on
again. Your program can either:
- Continue processing without the display station.
- Close the device file and open the file again.
- End."
