Return codes

In the case of an allocate that is about to be queued, use one of the

following:

UERCAQUE

Queue the allocate request.

UERCAPUR

Reject the allocate request with SYSIDERR.

UERCAKLL

Reject this allocate request with SYSIDERR. Purge all other

queued allocate requests and send an information message to the

operator console. CICS also returns SYSIDERR to all application

programs waiting on the purged allocate requests.

UERCAKLM

Reject this allocate request for the modegroup and return

SYSIDERR. Purge all other queued allocate requests for the

modegroup specified on this allocate request and send an

information message to the operator console. Retry the modegroup

after an interval.

UERCPURG

Task purged during XPI call.

In the case of a successful allocate following the use of UERCAKLL or

UERCAKLM, on a previous invocation of the exit, use one of the following:
