VMS Help INITIALIZE, /QUEUE, Qualifiers, /WSDEFAULT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /WSDEFAULT=n

    Defines for a batch job a working set default, the default number
    of physical pages that the job can use.

    The value set by this qualifier overrides the value defined in
    the user authorization file (UAF) of any user submitting a job to
    the queue.

    Specify the value of n as a number of 512-byte pagelets on Alpha
    systems or 512-byte pages on VAX. Note that OpenVMS rounds
    this value up to the nearest CPU-specific page so that the
    actual amount of physical memory allowed may be larger than the
    specified amount on Alpha. For further information, refer to the
    OpenVMS System Manager's Manual.

    If you specify 0 or NONE, the working set default value defaults
    to the value specified in the UAF or by the SUBMIT command (if it
    includes a WSDEFAULT value).

    You also can specify this qualifier for an output execution
    queue. Used in this context, the /WSDEFAULT qualifier establishes
    the working set default of the symbiont process for an output
    execution queue when the symbiont process is created.
