A single heading character may also be designated.
Example: To scan EAN and ITF (specified with a heading character) in
the following order--"EAN starting with 49" and "6- to 10-digit ITF starting
with 2," write as follows:
OPEN "BAR:" AS #1 CODE "&","A:49",
"I:6-10;2"
(4) Scanned codes will be outputted in the order specified to 1stline,
2ndline, or 3rdline.
Example: To output "EAN-8 starting with 12" and "EAN-8 starting with 21"
in this order, write as follows:
OPEN "BAR:" AS #1 CODE "&","A:B12","A:B21"
or
OPEN "BAR:" AS #1 CODE "&","A:B12,B21"
However, if the same code type, same heading character(s), and same
number of digits are specified to 1stline, 2ndline, or 3rdline as
given below, then the output order is indefinite.
OPEN "BAR:" AS #1 CODE "&","I:6;49",
"I:6;49"
or
OPEN "BAR:" AS #1 CODE "&","I:6;49,6;49"
For instance, the output order of ITF "495678" and ITF "498765" is indef-
inite in the above program.
(5) If codes whose code type and data are the same between codes as
shown below:
EAN-13 "4912345678901" at the 1st line
EAN-13 "1200000000000" at the 2nd line
EAN-13 "4912345678901" at the 3rd line
The above codes cannot be read if the following specification is defined:
OPEN "BAR:" AS #1 CODE "&","A:A49","A:A12",
"A:A49"
or
OPEN "BAR:" AS #1 CODE "&","A:A49,A12,A49"
