How do I create a BUFR message with random values?

For testing or development work, it can sometimes be useful to create a BUFR message from an existing Table D sequence, with only "bogus" or random values. The command to do this is:

bufr_encoder -sequence <sequence_number> -def_values -nbsubset <number> -outbufr <filename>

Where sequence_number is a valid Table D entry, such as "307080".

The switch -nbsubset indicates the desired number of subsets and may be omitted if only one subset is required.
