JCL/TSO Events and Actions

For each event, this section defines the key (but not all) inputs and outputs and the actions that can be requested for the event. The following actions apply to all events:

• The action-continue action code (which is the default action code) indicates to JCL/TSO that it should continue with normal processing as if the exit had never been invoked for that event..
• The action-shut-exit action code indicates to JCL/TSO that it should stop calling the user exit for all future events in this process for the current job or TSO session. This is intended as a performance aid. The user exit should still be coded so that it can receive future events and ignore them using the default action code action-continue.

The event names listed below correspond in part to the level-88 name assigned to the event code. Similarly, action code names listed correspond in part to the level-88 name assigned to the action code. Having access to the mfjdxit.cpy file will help your understanding of the facilities being described here.
