The simple way is to set up second display file (duplicate of the main display file) that will only be used when the user hits the function key F19. Your program should drop into a loop that reads the second display file, rather than doing an EXFMT, use a write, then a read to the display file. This read will be against the second display file created like this:
CRTDSPF FILE(MYLIB/SECONDDSPF) SRCFILE(MYSRCLIB/QDDSSRC) WAITRCD(15)
This will cause your program to wait for 15 seconds before returning. When the file returns, check to see if the user hit F3 or F12. If they did, drop back to the original routine. If not, reload the subfile and write/read again.
