C> THIS SUBROUTINE WRITES BUFR TABLE (DICTIONARY) MESSAGES
C>   ASSOCIATED WITH THE BUFR FILE IN LUNDX TO THE BUFR FILE IN LUNOT.
C>   BOTH UNITS MUST BE OPENED VIA PREVIOUS CALLS TO BUFR ARCHIVE
C>   LIBRARY SUBROUTINE OPENBF, AND IN PARTICULAR LUNOT MUST HAVE
C>   BEEN OPENED FOR OUTPUT.  THE TABLE MESSAGES ARE GENERATED FROM
C>   ARRAYS IN INTERNAL MEMORY (MODULE TABABD).  LUNDX CAN BE THE
C>   SAME AS LUNOT IF IT IS DESIRED TO APPEND TO LUNOT WITH BUFR
C>   MESSAGES GENERATED FROM ITS OWN INTERNAL TABLES.
