This helps diagnose barcode reader errors. If the program reports an error, reenter the barcode to be sure that a data entry error was not the cause of the message. When barcodes are the wrong length, when they are missing start or stop bars, or when the checksum is incorrect, you may be attempting to decode a fragment of a longer barcode. The debug versions are helpful in decoding barcode fragments since they decode the barcode and then attempt again with the view shifted right one bar at a time until each of the 5 cluster positions has been tested. Sometimes a barcode fragment lacking some initial bars can be read this way.
