Search backward for a string
B1 Search backward for “s” string from the current cursor position, leaving cursor
pointing to “s” string. Syntax = B1nnnnS where nnnn is the string length (up to
9999), and S consists of the ASCII hex value of each character in the match string.
For example, B1000454657374 will search backward for the first occurrence of the
4 character string “Test.”
Refer to the ASCII Conversion Chart (Code Page 1252), beginning on page 300 for
decimal, hex and character codes.
Search forward for a non-matching character
E6 Search the input message forward for the first non-“xx” character from the current
cursor position, leaving the cursor pointing to the non-“xx” character. Syntax = E6xx
where xx stands for the search character’s hex value for its ASCII code. Refer to the
ASCII Conversion Chart (Code Page 1252), beginning on page 300 for decimal, hex
and character codes.
E6 Example: Remove zeros at the beginning of barcode data
This example shows a barcode that has been zero filled. You may want to ignore the
zeros and send all the data that follows. E6 searches forward for the first character
that is not zero, then sends all the data after, followed by a carriage return. Using
the barcode above:
Command string: E630F10D
E6 is the “Search forward for a non-matching character” command
30 is the hex value for 0
F1 is the “Send all characters” command
0D is the hex value for a CR
The data is output as:
37692
<CR>

E7 Search the input message backward for the first non-“xx” character from the
current cursor position, leaving the cursor pointing to the non-“xx” character.
Syntax = E7xx where xx stands for the search character’s hex value for its ASCII code.
Refer to the ASCII Conversion Chart (Code Page 1252), beginning on page 300 for
