Check for non-numeric character
ED
Check to make sure there is a non-numeric ASCII character at the current cursor position. The
format is aborted if the character is numeric.
ED Example: Only output the data if the barcode begins with a letter
If you want only data from barcodes that begin with a letter, you can use ED to check for the
letter.
Command string:
EDF10D
ED
is the “C
heck for a non-
numeric character” command
F1 is the “Send all characters” command
0D is the hex value for a CR

the next data format, if there is one, will be used on
this data. If there is no other format, the format fails and the raw data is output as
1234AB
.
If this barcode is read:
the data is output as:
AB1234
<CR>
