C Command - Counter

The C command is used in forms that require se- quential numbering. When initializing counters, they must be defined in order (e.g. C0 first, C1 second...).

Field justification (p3) affects the printing of counter data. When L, R or C are selected, the counter field is the width of p2 value. Data will justify within the counter (p2) field per the se- lected p3. The N parameter will print the mini- mum number of characters. See programming example 13 in Appendix H.

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.

If the starting value of a counter is “1", then no lead- ing zero padding will be added. If the starting value is “01”, then the counter will be padded, up to the maximum number of digits (p2), with zeros.

Example: C0,10,L,+1,"-Enter Serial Number:"￿

Nonvolatile Memory

This feature is useful when the counter field rep- resents a serial number (or others types of num- bers) that should never be repeated. This feature allows for automatic retrieval and incre- menting (or decrementing) of the previous counter value used every time a form is re- trieved (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.

Single Digit Add or subtract a single digit from the recalled Summation with counter value in a form. If form recalled counter Counters C0 had a value of 3, then processing C0+1 would yield a value of 4 and C0-2would yield a

value of 1.
