Field justification (p
3
) affects the printing of counter data. When L, R or C are selected, the
counter field is the width of p
2
value. Data will justify within the counter (p
2
) field per the
selected
p
3
. The N parameter will print the minimum number of characters.
To print the contents of the counter, the counter number is referenced in the “DATA” field of
the A (ASCII text) or B (Bar Code) commands.
Note • If the starting value of a counter is “1“, then no leading zero padding will be added. If
the starting value is “01”, then the counter will be padded, up to the
maximum number of
digits (
p
2
), with zeros.
Example 1 •
C0,10,L,+1,"-Enter Serial Number:"↵
Example 2 • Saving and Protecting Consecutive Numbers in Nonvolatile Memory
This feature is useful when the counter field represents a serial number (or others types of
numbers) that should never be repeated. This feature allows for automatic retrieval and
increment (or decrement) of the previous counter value used every time a form is retrieved
(and printed).
By placing one minus sign as the first character of the prompt, the prompt will appear only
once after the form is retrieved, thereby protecting the integrity of the data.
Example 3 • Single Digit Summation with Counters
Add or subtract a single digit from the recalled counter value in a form. If form recalled
counter C0 had a value of 3, then processing C0+1 would yield a value of 4 and C0-2
would yield a value of 1.
