Match String
This command looks for a “match” between a data string designated in the
data editing formula and a data string in the data scanned by the reader. When
this feature is enabled, the only data sent to the host will be data that contains
the matched data string. The first two digits indicate the position in the
scanned data at which the match is to begin. Up to 60 characters can then be
entered to specify the actual string to be matched. If you need to match more
than one character string, simply add another match command to the formula.
(This command is optional.)
SELECTION CODE: JE
Two Digits for Position at which to Begin Match
Up to 60 Characters for Match String
EXAMPLE:
To begin the match string at position 8 and designate the match string as
ABCDE, enter:
... JE<ENTER>0<ENTER>8<ENTER>A<ENTER>B<ENTER>
C<ENTER>D<ENTER>E<ENTER> ...
This means that input data “1234567ABCDE” will match the data string in
the Match String formula and will therefore be considered valid.
Note: The first position is 01, not 00.
Create a Data Field
This command allows you to create a data field that begins with the first
position in the scanned data and extends a specified number of characters.
For instance, if the new data field is to be eight characters long, the undivided
field of data will be divided into two fields, the first eight characters long, and
the second the remaining data characters.
SELECTION CODE: JF
Two Digits for Position at which First Data Field Ends
EXAMPLE:
In scanned data 15 characters long, to create a first data field of 7 characters
and a second data field of 8 characters, enter:
... JF<ENTER>0<ENTER>7<ENTER> ...
This means that input data “1234567ABCDEFG” will divide into two fields:
1234567 and ABCDEFG.
