File control quiesce send exit XFCQUIS

The XFCQUIS global user exit is invoked on completion of a VSAM RLS quiesce or
unquiesce of a data set that was requested either by a CEMT or EXEC CICS SET
DSNAME QUIESCESTATE command.
The exit is invoked regardless of whether the QUIESCESTATE action has
completed successfully or unsuccessfully. This enables you to perform, or schedule,
any processing that cannot take place until quiesce or unquiesce processing has
finished.
