Deleting the DESERV Exit

An application that has established a DESERV exit can delete the currently active exit by issuing the DESERV macro with FUNC=EXIT. You can specify the following:

Table 1. Deleting the DESERV Exit
For this parameter	specify this:
EXIT_SCOPE	(application dependent)
EXIT_OPTION	DELETE
EXIT_DST	Currently active DST to be deleted
EXIT_PREV_DSTPTR	The DST to become active
Note: The address of the DST must match that of the currently defined DST. If the addresses do not match, DESERV returns error return and reason codes to indicate the DELETE operation has failed and the active DST remains unaffected.

For a task related exit, the DESERV exit is implicitly deleted when the task ends. A global exit can only be explicitly deleted by issuing a DESERV FUNC=EXIT call.
