Codabar is a non-continuous barcode without check character. Its character set is composed of '0' to '9', 'A', 'B', 'C', 'D', '$', '-', ':', '/', '.', '+'. 'A' to 'D' are eligible only for start/stop characters. Though the characters 'T', 'n', '*', 'e' may be used instead of 'A', 'B', 'C and 'D', you cannot directly use them to set data. You may, of course, display them (as well as any other characters) through the Caption property if you are using the Barcode Control.

The following default values are used:

    - wide/narrow bar ratio = 3
    - intercharacter gap = 2 * narrow bar
