The IXCQUIES macro allows an active XCF member to place itself in a quiesced state. In a quiesced state, the member can no longer use the monitoring and signalling services of XCF. If active members have a group user-routine, XCF notifies those members that the member is quiesced. XCF delivers outstanding messages sent by the member, and discards undelivered messages that were sent to the member.

IXCQUIES requires that the member have permanent status recording established.
