Code 128 Subsets
The Code 128 character subsets are referred to as Subset A, Subset B, and Subset C. A subset
can be selected in these ways:
• A special Invocation Code can be included in the field data (
^FD) string associated with
that bar code.
• The desired Start Code can be placed at the beginning of the field data. If no Start Code is
entered, Subset B are used.
To change subsets within a bar code, place the Invocation Code at the appropriate points
within the field data (
^FD) string. The new subset stays in effect until changed with the
Invocation Code. For example, in Subset C,
>7 in the field data changes the Subset to A.
Table 6 shows the Code 128 Invocation Codes and Start Characters for the three subsets.
