Program check handling

The occurrence of a program check in the trap exit is detected by the recovery routine in DFHTRPT. This then:

  1. Marks the exit as unusable
  2. Issues the message DFHTR1001 to the system console
  3. Takes a CICS® system dump with dump code TR1001, showing the PSW and registers at the time of the interrupt
  4. Continues (ignoring the exit on future invocations of the trace domain).

To recover from this situation, execute the commands given above for replacing the current version of the exit routine.
