CLI_Routines

   The command language interface (CLI) routines process command
   strings using information from a command table. A command table
   contains command definitions that describe the allowable formats
   for commands. To create or modify a command table, you must
   write a command definition file and then process this file with
   the Command Definition Utility (the SET COMMAND command). For
   information about how to use the Command Definition Utility,
   see the VSI OpenVMS Command Definition, Librarian, and Message
   Utilities Manual.
