Customizing the Exit

This exit can take the data passed to it to determine what IMS region to use for the request being processed and the LTERM to be used.

Ensure DESRC points to the relevant return code. Return control to the caller using the value passed in Register 14 at entry. All registers except Register 15 must be restored. Results are unpredictable if invalid data is returned. Register 15 should contain the return code.

Note: Be sure to use the source that corresponds to your IMS release.
