Use of the Comma Key

The comma key can be used to delimit data fields. In the normal course,

scanning a barcode representing A1000 followed by typing 10 ENTER on the

keyboard would produce in memory:

A1000

However, by scanning A1000 then typing , 10 ENTER, memory would

contain:

A1000,10

When downloading to your computer, having related data on the one line

separated by a comma may make software programming easier.

Editing Data

Because barcodes themselves usually contain error checking, no facilities are

provided to alter barcode scans in memory.

If entries are made on the keypad but ENTER has not been pressed, characters

may be deleted by using the backspace « key. Once ENTER has been pressed,

the line just typed cannot be edited.

Editing data on a two-line display is impractical. Accordingly, we suggest you

adopt a method of identifying incorrect data, downloaded from the BCR, in the

programs used in the host computer system. Probably the most common

problem will be encountered during an inventory, where an identifying barcode

may have been scanned, but the quantity typed in is too high or too low. One

answer might be to re-scan the barcode and type in the correct quantity. When

the data is downloaded to the host computer, the receiving program could be

designed in such a way that when it finds a barcode scanned more than once, it

accepts as valid only the last read (with its associated quantity).

Your dealer will be happy to assist with suggestions to suit your application.
