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 field is
defined by the number of characters in the STEPMASK field; the
STARTDATA field cannot contain more characters than used in the
STEPMASK field.
Linked and unlinked masking of subfields within the STARTDATA is
defined by the L value in the STEPMASK field. L indicates linked but
non–incremental data in the corresponding position of the STARTDATA
field; any alpha character other than L in the STEPMASK field indicates a
non–incremental, non–linked STARTDATA subfield.

The examples on the following pages illustrate incremental alphanumeric
data fields. All cases in the examples use a repeat count parameter value of 1
and a reset count parameter value of 0. The three vertical dots illustrate the
natural progression for each column and unit of data based on the
incremental count and its impact on linked and unlinked data fields.
