 pagcnt

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read only
    mechanism:    by value
    Signed adjustment value specifying the number of pages (on VAX
    systems) or pagelets (on Alpha systems) to add to (if positive)
    or subtract from (if negative) the current working set limit. The
    pagcnt argument is this signed longword value.

    Note that, on Alpha systems, the specified value is rounded up to
    an even multiple of the CPU-specific page size.

    If pagcnt is not specified or is specified as 0, no adjustment
    is made and the current working set limit is returned in the
    longword specified by the wsetlm argument (if this argument is
    specified).

 wsetlm

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       write only
    mechanism:    by 32- or 64-bit reference (Alpha)
    mechanism:    by 32-bit reference (VAX)
    Value of the working set limit, in pages (on VAX systems) or
    pagelets (on Alpha systems), returned by $ADJWSL. The wsetlm
    argument is the 32-bit address (on VAX systems) or the 32- or
    64-bit address (on Alpha systems) of this longword value. The
    wsetlm argument receives the newly adjusted value if pagcnt is
    specified, and it receives the prior, unadjusted value if pagcnt
    is not specified.
