Alphanumeric Field Separator

Purpose: Increments or decrements alphanumeric characters within a field-separated

region. You must enclose the data between two sets of <GS> commands:

Syntax: <GS>

Alphanumeric characters are 0 to 9 and A to Z. The order of the characters

is 0, 1, 2...8, 9, A, B, C...Y, Z, 0, 1...9, A, B....

Notes: You may have more than one region in a field as long as they do not

overlap. Each region independently increments or decrements according to

the increment or decrement value specified for the field. The length of

data does not change. Rather, the values increment or decrement as in an

odometer. For example, 9 increments to 0, and Z increments to A.

This command marks the region of characters to increment or decrement,

but it does not actually increment or decrement. The printer ignores any

non-alphanumeric characters within this region.

The following example illustrates the Alphanumeric Field Separator

command:

<STX><CR>Increment Field<ETX>

<STX><CR>Decrement Field<ETX>
