For a BUFR file containing GTS bulletins with BUFR BUOY messages, the following output to STDERR was produced when using option --strict_checking 1:
BUFR.pm WARNING: Compression set in section 1 for one subset message at /metno/local/bin/bufrread.pl line 143 BUFR.pm WARNING: Compression set in section 1 for one subset message at /metno/local/bin/bufrread.pl line 143 BUFR.pm WARNING: Compression set in section 1 for one subset message at /metno/local/bin/bufrread.pl line 143 BUFR.pm WARNING: Compression set in section 1 for one subset message at /metno/local/bin/bufrread.pl line 143 BUFR.pm WARNING: CCITTIA5 minval not all bits set to zero but '000000000000' at /metno/local/bin/bufrread.pl line 143 BUFR.pm WARNING: CCITTIA5 minval not all bits set to zero but '000000000000' at /metno/local/bin/bufrread.pl line 143 BUFR.pm WARNING: Compression set in section 1 for one subset message at /metno/local/bin/bufrread.pl line 143
Output to screen is exactly as if --strict_checking had not been used (in which case nothing is printed to STDERR). If using --strict_checking 2, however, the problematic messages are left out from output to screen (which therefore starts with Message 6), while output to STDERR now changes to (the actual CCCC has been replaced with XXXX):
