C
Counter
Description The counter (C) command defines one of 10 automatic counters used in
consecutive numbering applications (i.e. serial numbers). Counters must be defined after
variables.
For Numeric Serialization Only. The counter function does not support Alpha or Alpha-
Numeric Serialization.
The C command is used in forms that require sequential 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
selected p3. 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.
