PL/I considerations

For those PL/I conditions that do not raise the ERROR condition as part of their implicit action, PL/I requires that a message be issued. For these conditions, the message is issued regardless of the setting of TERMTHDACT. Therefore, messages can be delivered even when TERMTHDACT(QUIET) is set.

If the condition remains unhandled (for example, the PL/I FINISH condition is still regarded as unhandled after normal return from a FINISH ON-unit), and the application terminates, the message associated with the condition is not issued again at termination.

For more information about TERMTHDACT, see z/OS Language Environment Debugging Guide and z/OS Language Environment Programming Reference.
