Codabar
Codabar is a self-checking, discrete symbology which encodes the numbers and the $ : / . + - characters. Codabar is unusual in that the barcode characters have differing widths. Also the symbology allows for several combinations of start and stop character.
Start and stop characters are usually A for start and C for stop,
This code must begin with a start character and must end with a stop character. Start and stop characters are usually A for start and C for stop, and dFont reproduces these as the start character § (Chr$(167)) and the stop character ¬ (Chr$(172)).
However, any alternative may be chosen from the list below - although not all Codabar readers recognise all these combinations.
Allowed start/stop codes: A B C D E N T *
All codes prepared to create a Codabar symbol must include a start and stop character.
Codabar does not use check digits, so there is no entry for Codabar in the dFont program.
