VMS Help ENABLE, AUTOSTART, Qualifiers, /NAME_OF_MANAGER  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /NAME_OF_MANAGER=name

    Specifies the name of the queue manager controlling the autostart
    queues you want to enable. The qualifier allows the autostart
    feature to be used differently for different sets of queues.

    If the /NAME_OF_MANAGER qualifier is omitted, the default queue
    manager name SYS$QUEUE_MANAGER is used.

    For more information on multiple queue managers, refer to the
    chapter on the queue manager in the OpenVMS System Manager's
    Manual.
