The increment amount is defined by the numeric value of the STEPMASK data. For example, a STEPMASK value of 1 increments the STARTDATA by 1; a STEPMASK value of 2 increments the STARTDATA by 2.

The maximum number of characters allowed in the STARTDATA is defined by the number of characters in the STEPMASK field and depends on the specific type of bar code; the STARTDATA field cannot contain more characters than used in the STEPMASK field and can only contain the number and type of characters allowed by the bar code.

Linked and unlinked masking of subfields within the STARTDATA is defined by using the L value in the STEPMASK field. L indicates linked but nonincrementing data in the corresponding position of the STARTDATA field. Any alphanumeric character other than L in the STEPMASK field indicates a nonincrementing, non±linked STARTDATA subfield.

The following examples illustrate incrementing of bar code data fields. All cases in the examples use a repeat count parameter value of 1 and a reset count parameter value of 0. Incremental bar code data is generated identically to incremental alphanumeric data except the IGP/PGL does not add leading spaces to bar code data.

NOTE: In the following bar code examples, the value of the data is shown automatically incrementing. In practical applications, the bar code itself would print corresponding to the incremented data as shown in the Auto Increment Fields Example on page 6±14 in the ªCommandsº chapter.
