           Macros definitions used to generate the MTRTABLE.
           In open code
              &label MTRTABLE
           Will generate the MTP Routing Table.
           Internally the MTRENT macro is used to generate a table
           entry. To modify the table, specify MTRENT macros as
           required at the end of MTRTABLE.
         *  MTRSTART: Begin the MTRTABLE
         *  MTREND: Complete the MTRTABLE
         * Define the router table
         * To add additional entries simply code new MTRENT macro calls
