{       This is the 223 agent used by IFP$SUPPRESS_CURSOR_POS_ECHOPLX
{   to write the job pageable variables
{   IIV$SUPPRESS_CURSOR_POSITIONING and IIV$SUPPRESS_ECHOPLEXING,
{   since it cannot write them directly.  IIM$ST_PUT reacts to the
{   setting of these variables by setting the
{   suppress_end_line_positioning and/or the suppress_echoplexing bit
{   in the header of the next non-partial output data message.
