  Syntax:  SET COMMAND LANGUAGE command_language

  Sets the command language to the specified syntax.

  The current command language options are PORTABLE or VMS.  The
  PORTABLE option enables the portable command- language parser.  On
  VMS, the VMS option enables the VMS-only Command Language Interpreter
  (CLI) parser.  The VMS option is not available on ULTRIX.
