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

    PQL_MWSDEFAULT sets the minimum default working set size for a
    process created by the Create Process ($CREPRC) system service or
    the DCL command RUN (Process).

    This value overrides a smaller quantity that is set for a user in
    AUTHORIZE.

    PQL_MWSDEFAULT has the AUTOGEN and GEN attributes.
