#  This script generates BUFR messages corresponding to a given user DX
#  (BUFR dictionary) table and appends them to a given BUFR data file.
#  It is primarily intended for use when implementing DX table changes
#  to a BUFR tankfile in the NCEP observational database.
#
#  NOTE: The script is set up to run in the Bourne shell. If you are a

#  <BUFRfile>  [path/]filename of BUFR data file to be appended
#  <DXtable>   [path/]filename of DX dictionary table
