I'm not understanding how to compute the check digit for a code 128 type c bar code,
First, I guess, is this simple question: Does the DDS BARCODE keyword have an option to do this? We are on (stuck at) v5r4. I didn't see anything that would generate the check digit. I have a sample, printed, of a 7 digit number (1234567).
My efforts, thus far, have been:
Move 105 to a counter (start type c)
Add 12.
Add product of (34 * 2)
Add product of (56 * 3)
Add 104 (start type c)
Add 23
Divide counter by 103, use remainder to look up the check digit.
The resulting bar code (compared to my reference) is missing some bars on the right side, like a digit. But, what is missing?
Can anybody shed some light on this for me?
Thanks,
John McKee
