Custom Character Classes

A custom character class (CCC) is a string of up to 50 printable characters that is associated with a template variable. When a template variable is specified in a template only characters in the associated CCC string will be allowed in the specified character position. The variable \G is associated with custom character class 1 (CCC1) and the variable \H is associated with custom character class 2 (CCC2). Table F-11gives some examples of how CCCs are used. The CCC strings must specify at least one character for the associated variable to be used in a template.

OCR Check Characters

OCR can be configured to use either a Modulo 10 or Modulo 36 check digits using the PDT parameters. A check digit is used to verify the contents of a bar code by calculating the total of the data. By default, OCR is configured to use Modulo 10 check digits. This setting is global to all check digits. The following must be true for the placement of a check digit to be considered valid:

•The check digit must be put at the end of a row.

•There can be no more than 1 check character in a row.

•Rows with check digits can only have the characters 0-9 and A-Z.
