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

       /WSQUOTA=n

    Defines for the batch job a working set quota, the amount of
    physical memory that the job is guaranteed. If the queue on which
    the job executes has a nonzero working set quota, the smaller of
    the specified job and queue values is used. If the queue on which
    the job executes has a working set quota of 0, the smaller of the
    specified job or the value established in the user authorization
    file (UAF) is used.

    Specify the value of n as a number of 512-byte pagelets on
    Alpha or 512-byte pages on VAX. Note that OpenVMS systems round
    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 specified queue or UAF value is used. Working set quota
    values must range between the numbers specified by the system
    parameters PQL_MWSQUOTA and WSMAX.
