In this example, the data in positions 1 and 3 can be anything; but position 2 must be an “S”.
2. UPC/EAN Check digit verification for keyed-in data
The second function of the Data ID field is to have the Terminal verify the check digit on an UPC or EAN
bar code when the data has be entered on the Terminal keypad (not scanned). This scenario happens often
when bar codes are damaged or missing and the data has to be entered by hand. To avoid errors when the
data is keyed in, the Terminal will calculate a check digit for the data and compare it to the check digit that
was keyed in. If the two digits do not match, the Terminal generates the following error message:
INVALID INPUT
HIT ANY KEY_
To use this feature, enter the following characters at the DATA ID prompt:
U10 - Use this to verify UPC 12 or 8 digit entries
E10 - Use this to verify EAN 13 or 8 digit entries
B10 - Use this to check for both UPC and EAN 13, 12 or 8 digit entries.
UPC/EAN 2 and 5 digit supplements are not supported.
3. Display Date and Time
Normally, a date or time stamp statement does not display any data when executed but sometimes you may
want the user to see the data being written to the data file. To display the date and or time, use:
DIS
in the DATA ID field.
4. Prevent duplicate entry of data
To prevent the duplication of data entered at a particular statement, use
DUP
in the DATA ID field. During Data Collection, if data is entered at a statement prompt that had been entered
previously for the same statement prompt, the user will see the message:
DUPLICATE ACCESS
PRESS ENTER_
Press ENTER to discard the data and repeat the statement prompt. To accept the data and write it to the data
file, press the F1 key. The program will then advance to the next statement prompt.
5. Compare Data
The Data ID field is used to compare entered data when the Compare statement type C is used. Enter the
statement number you want to compare the currently entered data to. For example, if you wanted to
compare the data you scanned in statement 2 to the data you scanned in statement 1, you would choose the
