I am writing an application in RPG which will cause a handheld scanner to beep if certain conditions of the item scanned are met. I would like to identify two distinct conditions with one or two beeps. The difficulty is in generating two beeps. I set up one screen definition with an overlay and alarm and execute a WRITE. It does not activate the alarm. When I replace the WRITE with an EXFMT, the alarm sounds but that holds the blank screen. Pressing `Enter` will display the actual screen.

The ALARM sounds (if supported by the device) when the record format is DISPLAYED--not when it is written. Default behaviour is for writes to be deferred until a request for user input occurs. Solutions are:
1) Force the ALARM record format to the device: FRCDTA DDS keyword
2) Don't defer writes: DFRWRT(*NO) on CRTDSPF or CHGDSPF
