pagcnt

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read only
    mechanism:    by value
    Signed adjustment value specifying the number of pagelets 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 and Integrity server 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
    Value of the working set limit, in pagelets , returned by
    $ADJWSL. The wsetlm argument is the 32- or 64-bit address 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.
