Code 128 (
K)
Syntax :
K[:[mini.no.digits[-max.no.digits]]
[,[mini.no.digits[-max.no.digits]]]
[,[mini.no.digits[-max.no.digits]]]]
where
mini.no.digits and max.no.digits are the minimum and maximum
numbers of digits for bar codes to be read by the BHT, respectively.
They should be a numeral from 1 to 99, excluding start/stop characters and
check digit. They should satisfy the following condition:
mini.no.digits ≤ max.no.digits
If both of mini.no.digits and max.no.digits are omitted, then the
default reading range is 1 to 99 digits. If only
max.no.digits is omitted,
the BHT can only read the number of digits specified by mini.no.dig-
its
.
OPEN "BAR:" AS #1 CODE "K:6-12"
Neither start/stop characters nor check digits will be transferred to the barcode
buffer.
If the BHT reads any bar code consisting of special characters only (such as
FNC, CODEA, CODEB, CODEC and SHIFT characters), it will not transfer the
data to the barcode buffer. The beeper sounds only if it is activated.
FNC characters will be handled as follows:
(1) FNC1
The BHT will not transfer an FNC1 character placed at the first or second
character position immediately following the start character, to the barcode
buffer. FNC1 characters in any other positions will be converted to GS
characters (1Dh) and then transferred to the barcode buffer like normal
data.
If an FNC1 immediately follows the start character, the bar code will be
recognized as EAN-128 and marked with
W instead of K.
(2) FNC2
If the BHT reads a bar code containing an FNC2 character(s), it will not
buffer such data but transfer it excluding the FNC2 character(s).
(3) FNC3
If the BHT reads a bar code containing an FNC3 character(s), it will regard
the data as invalid and transfer no data to the barcode buffer, while it may
drive the indicator LED and beeper (vibrator) if activated with the
OPEN
statement.
