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

    PQL_DJTQUOTA sets the default job table byte count quota for a
    process created by the Create Process ($CREPRC) system service or
    the DCL command RUN (Process). PQL_DJTQUOTA specifies the number
    of bytes of paged pool allocated to the job table. The default
    value is usually adequate, unless a large number of job logical
    names or temporary mailboxes are used.

    PQL_DJTQUOTA is a DYNAMIC parameter.
