Programming considerations

Consider the following when coding your configuration change exit routine:
  • The exit routine is required to save and restore the contents of GPR 13.
  • The exit routine must reside in common storage.
  • The exit routine should not wait for asynchronous work to complete. Otherwise, system deadlocks might occur.
  • Code a different configuration change exit routine for each type of notification, rather than coding one exit routine to respond to all notification types.
