How can I tell within my program if the user has closed their emulator
session? We have situations where a record is locked and the users are
closing their emulators and this is causing data integrity issues.

What is the QDEVRCYACN sysval set to?

If a message is sent to the program, you can trap it it by putting a MONITOR/ON-ERROR around the EXFMT statement. There's a particular status code (I think it's 1251, but don't quote me on that) that will come up.


              MONITOR;
                 exfmt MYSCREEN;
              ON-ERROR 1251;
                 exsr Recovery;
              ENDMON;

Though, I can't seem to visualize why this would cause an integrity issue, unless it's in the middle of updating something and getting cut off at that point? But that shouldn't happen, the error should occur when it tries to work with the screen.
