       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
