Printronix ThermaLine Series manual ±1. Increment Alphanumeric, Stepmask Start Data

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.

Table 4±1. Increment Alphanumeric

STEPMASK	START DATA	Character Type and Function
0 ± 9	A ± Z	Alpha characters incremented by amount
		in STEPMASK field
0 ± 9	0 ± 9	Numeric characters incremented by
		amount in STEPMASK field
0 ± 9	Space	Same character type as character in the
		next right adjacent, linked increment posi-
		tion. Character type will be numeric if in
		least significant position.
0 ± 9	Not A ± Z or 0 ± 9	Error
Not 0 ± 9 or L	Any	Non±incrementing alphanumeric
		character
L	Any	Linked, non±incrementing alphanumeric
		character

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.
