{
{   The purpose of this request is to interpret a string as one or more
{ commands.
{
{   This request differs from the clp$include_line request in that the latter
{ builds a whole new "input control block" in which to process the commands and
{ control statements, whereas clp$include_command processes them in the context
{ of the current "input control block".
{
