I have code given to me by a customer written in cobol. It is used to create a check digit at the end of a row of digits. It is either mod 7 or mod 10. I am not very familiar with cobol and was wondering if anyone had any examples of either so maybe I could compare the code and see which it is. Also i will be converting this to VB so if you have any examples of VB check digit it would be greatly appreciated.
