Optional parameters

MHLQ(mhlq): Specifies the high-level qualifier of the master session control data set. The default is SYS1.
IMMEDIATE: When you issue the XEND command by using a master session name, the command is processed on all XRC sessions that are coupled to the master session. In this instance, the IMMEDIATE parameter is processed as ATTIME equal to a time that will permit all coupled sessions to be ended at the same consistency time.
ATTIME: When the XEND command is issued using a master session name, the ATTIME parameter is processed as global ATTIME if no component session has received an application update timestamp past the requested timestamp. If any session has passed the time, the command is rejected.
DRAIN: Specifies that all sessions in a coupled master session determine a ‘drain time’. When you specify a XEND command by using a master session name, the DRAIN parameter is processed as ATTIME by using the latest component drain time.
CANCEL: Specifies that XRC cancel the previous master XEND command that has not yet processed. The CANCEL option cancels a pending XEND command that was issued to the master session but not yet processed. If the XEND command has started processing on any session, the CANCEL request fails. (The CANCEL option is valid only when there is a pending XEND command.)
NOVERIFY: Specifies that XRC not issue message ANTT0022A, which prompts the user to confirm that XRC should continue to process the command. If you select this option, XRC immediately processes the command to end the master session without waiting for verification.
MSGROUTEID: Specifies the user ID to which XRC messages that are associated with the processing of this command are routed. If the specified user ID is logged off, TSO saves messages in the TSO BRODCAST data set and displays them after the next logon.
Note: Messages issued by the initial command parser routine are sent to the user ID that issues the TSO command.
