/sys$common/syshlp/helplib.hlb JOB, Qualifiers, /WSDEFAULT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /WSDEFAULT=n

    Defines a working set default for the batch job; the /WSDEFAULT
    qualifier overrides the working set size specified in the user
    authorization file (UAF).

    Specify the value of n as a number of 512-byte pagelets on Alpha
    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. The value n can be any integer from 1 to 65,535, 0, or
    the keyword NONE. For further information, refer to the OpenVMS
    System Manager's Manual.

    Use this qualifier to impose a value lower than the base queue
    value established by the system manager or lower than the value
    authorized in your UAF. A value of 0 or the keyword NONE sets the
    default value to the value specified either in your UAF or by the
    working set quota established for the queue. You cannot request a
    value higher than your default.
