                    boolean extendedMode)

Creates a reader that can be configured to check the last character as a check digit, or optionally attempt to decode "extended Code 39" sequences that are used to encode the full ASCII character set.

Parameters:

usingCheckDigit - if true, treat the last data character as a check digit, not data, and verify that the checksum passes.

extendedMode - if true, will attempt to decode extended Code 39 sequences in the text.
