{
{   The purpose of this request is to interpret a string as a statement list.
{ The text in the line may not contain incomplete statements, e.g.  if a WHILE
{ statement is in the line, the corresponding WHILEND must also be in the line.
{
{   This request can be used on its own or in conjunction with the
{ clp$begin_utility request to initiate processing of the commands for a
{ utility.
{
{   This request differs from the clp$include_command request in that
{ clp$include_line builds a whole new "input control block" in which to process
{ commands and control statements, whereas clp$include_command processes them
{ in the context of the current "input control block".
{
{       CLP$INCLUDE_LINE (STATEMENT_LIST, UTILITY, ENABLE_ECHOING, STATUS)
{
{ STATEMENT_LIST: (input)  This parameter specifies the string to be
{       interpreted.
{
{ ENABLE_ECHOING: (input)  This parameter determines whether the interpreted
{       commands and statements may be echoed (TRUE) or not (FALSE).
{
{ UTILITY: (input)  This parameter specifies the name of the utility with which
{       the clp$include_line is to be associated.  Osc$null_name may be
{       specified to avoid association with any utility.
{
{ STATUS: (output)  This parameter specifies the request status.
