COUNT&
Field of Application Statement for creating a counter (Intermec Direct Protocol only).
Syntax COUNT& <sexp

<sexp

> is the type of counter parameter to be set:
START (start value)
WIDTH (minimum number of digits)
COPY (number of copies before update)
INC (increment/decrement at update)
STOP (stop value)
RESTART (restart counting at this value)
<nexp
1
> is the counter reference number (integers only)
<sexp
2
> is the parameter value
Remarks
This instruction can only be used in the Intermec Direct Protocol.
The counters can be used in text and bar code fi elds and are global, which
means that they are not connected to any special label or layout, but
will be updated at every execution of PRINTFEED statements where
the counter in question is used.
Counters are designated using positive integers, for example 1, 2, or 3. When
used for printing, they are referred to by “CNT<ncon>$” variables, where
<ncon> is the number of the counter as specifi ed by COUNT&, for example
CNT5$. A counter variable without a matching counter will be regarded
as a common string variable.
The value of the start, stop, and restart parameters decide the type of
counter (alpha or numeric). If different types of counter are specifi ed
in these parameters, the last entered parameter decides the type. Alpha
counters count A-Z whereas numeric counters use numbers without
any practical limit.
Counters are not saved in the printer’s memory, but will have to be recreated
after each power up. Therefore, it may be wise to save the COUNT&
statements as a fi le in the host.
START:
Decides the fi rst value to be printed. If a single letter is entered (A-Z), the
counter will become an alpha counter, and if one or several digits are entered
the counter will be numeric. Numeric values can be positive or negative.
Negative values are indicated by a leading minus sign.
Default: 1 (numeric) or A (alpha)
WIDTH:
This parameter can only be used in numeric counters and decides the
minimum number of digits to be printed. If the counter value contains a
lesser number of digits, leading zero (0) characters will be added until
the specifi ed number of digits is obtained. If the number of digits in the
counter value is equal to or larger than specifi ed in the width parameter, the
value will be printed in its entity.
Default: 1 (no leading zeros)
