We receive an alphanumeric string of 14 characters of data from our customers and we need to increment the last four numeric digits. The string is in the form of AB345678928976. We use the last four digits in a variable and work on it this way. Which works fine as I have set the variable as type INT. The problem is, we need now to combine them back together with the new last 4 digits and the original first 10 digits. So if we had done this on the example above, the last four digits would be different.
Any help would be appreciated.
