Number and letters (alphanumeric values)
I am doing an application that a part of it generates account numbers. This account number is fixed to a max of 4 spaces. Eg, "1234". I want the account number to have letters after the numbers. For example: "..., 9998, 9999, A000, A001,...".
Can you tell me how can I generate these? Is there a function already that does this?
Thanks for your help.
