Description

   This routine calls CLI$DCL_PARSE to establish a command table and
   a command to parse. It then calls TPU$PARSEINFO to build an item
   list for TPU$INITIALIZE.

   If your application parses information that is not related to the
   operation of TPU, make sure the application obtains and uses
   all non-TPU parse information before the application calls
   TPU$CLIPARSE. You must do this because TPU$CLIPARSE destroys all
   parse information obtained and stored before TPU$CLIPARSE was
   called.
