RECEIVE acknowledgment notification exit

If the sender of data requested acknowledgment, the RECEIVE acknowledgment notification exit (INMRZ05R) receives control after the acknowledgment has been sent. However, this exit does not receive control if exit INMRZ06R has suppressed the acknowledgment. If RECEIVE is processing several files, each with a request for acknowledgment, this exit is invoked multiple times during RECEIVE processing. The exit enables installations to notify the sender that an acknowledgment is waiting to be received by the sender. The sender can then receive the acknowledgment and free spool space.

Note: If RACF® is installed, your installation can activate security label checking. If your installation has activated security label checking, and the result of that check indicates the receiver is at a different security label than the sender is logged on with, exit INMRZ05R is invoked. However, the sender may not get the acknowledgment.
