{
{   The purpose of this request is to process the  monitor request
{  'syc$rc_fetch_offset_mod_pages'.  This monitor request returns to
{  job mode a list of segment offsets for all modified pages for a
{  given segment.
{   If the array is not large enough to hold all offsets for the modified
{  pages for the given segment, monitor will update the offsets_returned
{  field in the request block and the caller then should check and see
{  if he should re-allocate the array using the offsets_returned value.
{
{       MMP$MTR_FETCH_OFFSET_MOD_PAGES (RB)

{ RB: (input, output): This parameter is a record which contains the
{       information specifying whats offsets to return.  The offsets
{       and control information are returned in this parameter.
