Appendix J Code 128 bar code
K.1 Description of the CODE128 Bar Code
In CODE128 bar code system, it is possible to represent 128 ASCII characters and 2-digit numerals
using one bar code character that is defined by combining one of the 103 bar code characters and 3
code sets. Each code set is used for representing the following characters:

Code set A: ASCII characters 00H to 5FH

Code set B: ASCII characters 20H to 7FH

Code set C: 2-digit numeral characters using one character (100 numerals from 00 to 99) The
following special characters are also available in CODE128:

SHIFT characters
In code set A, the character just after SHIFT is processed as a character for code set B. In code
set B, the character just after SHIFT is processed as a character for code set A. SHIFT
characters cannot be used in code set C.

Code set selection character (CODE A, CODE B, CODE C).
This character switches the following code set to code set A, B, or C.

Function character (FNC1, FNC2, FNC3, FNC4)
The usage of function characters depends on the application software. In code set C, only
FNC1 is available.
