I've never understood why z/OS doesn't provide a command interface to CP. z/VSE does. Some things to think about for production guests: 1) Remove harmful commands from their repertoire. E.g. CP MODIFY COMMAND LOGOFF IBMCLASS * PRIVCLASS ABCDE removes LOGOFF from class G. (A too-simplistic example.) 2) Prevent CP DISCONNECT from hanging in CP READ by placing COMMAND SET RUN ON in the guest's directory entry 3) Prevent any CP READ fwhen the guest is disconnected from being fatal by placing COMMAND SET TIMEBOMB OFF in the directory entry.
