VMS Help START, /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.

    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 execution
    queue when the symbiont process is created.

    Specify the value of n as a number of 512-byte pagelets on Alpha
    or 512-byte pages on VAX. Note that the operating systems rounds
    up this value to the nearest CPU-specific page so that the
    actual amount of physical memory allowed may be larger than the
    specified amount on Alpha.

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