Library /sys$common/syshlp/uafhelp.hlb ADD, Qualifiers, /PGFLQUOTA  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /PGFLQUOTA=value

    Specifies the paging file limit. This is the maximum number of
    pages that the person's process can use in the system paging
    file. By default, the value is 32768 pages on VAX systems and
    50000 pagelets on Alpha systems.

    If decompressing libraries, make sure to set PGFLQUOTA to twice
    the size of the library.
