Codabar (NW-7) (
N)
Syntax:
N[:[mini.no.digits[-max.no.digits]][startstop][CD]
[,[mini.no.digits[-max.no.digits]][startstop][CD]]
[,[mini.no.digits[-max.no.digits]][startstop][CD]]]
where
mini.no.digits and max.no.digits are the minimum and maxi-
mum numbers of digits for bar codes to be read by the BHT, respectively.
They should be a numeral from 3 to 99 and 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 from the minimum number of digits specified in Sys-
tem Mode up to 99 digits.
If only
max.no.digits is omitted, the BHT can only read the number of
digits specified by
mini.no.digits.
start and stop are the start and stop characters, respectively. Each of
them should be an A, B, C, or D. If a question mark (?) is specified, it acts as
a wild card. The start and stop characters are included in the number of digits.
The A through D will be stored in the barcode buffer as a through d.
CD is a check digit. Specifying a C to CD makes the Interpreter check bar
codes with MOD-16. The check digit is included in the number of digits.
OPEN "BAR:" AS #1 CODE "N:8AAC"
To specify multi-line code scanning, the above syntax should be preceded by
an ampersand (
&) and should be repeated by the number of lines of codes to
be scanned. In multi-line code scanning, no question mark (?) should be
specified to startstop. (For detailed specifications of multi-line code scan-
ning, refer to the Multi-line code scanning
given on page 277.)
Example: To scan 3 lines of Codabar codes, write as follows:
OPEN "BAR:" AS #1 CODE "&","N:8","N:6","N:4"
or
OPEN "BAR:" AS #1 CODE "&","N:8,6,4"
