{    The purpose of this request is to get leveling data on the requesting
{ mainframe.  The procedure jmp$mainframe_get_leveling_data, which may be
{ modified by the site, is called to collect the information.  This routine
{ functions as a co-routine with the jmp$cluster_get_leveling_data request.
{ This request is called by the jmp$general_purpose_cluster_rpc request.
{
{       JMP$GET_LEVELING_DATA (TARGET_OPTIONS_P, DATA_AREA_P,
{             NUMBER_OF_DATA_PACKETS, STATUS);
{
{ TARGET_OPTIONS_P: (input)  A pointer to a sequence that contains the caller
{       information and options about what data is to be returned.
{
{ DATA_AREA_P: (input, output)  The area where the leveling data is written.
{
{ NUMBER_OF_DATA_PACKETS: (output)  This indicates the number of data packets
{       in the data_area_p sequence.  This request returns all data from one
{       mainframe in one data packet.  Therefore, this value will always be 1.
{
{ STATUS: (output) This is the status of the request.
