Yes, it is ASCII.What I am trying to do is show you how to convert characters, and pairs of characters, into the numeric values that it seems you are after.
What are you really trying to do?

Okay... I have a 4x3 keypad and a range of other devices connected to my arduino mega 2560. I am trying to design a set of cases within a switch statement,.ie Case 10: case 11: case 12: to each perform seperate functions, HOWEVER the case requirements ("10"),("11") are based upon the KEYPAD ENTRY, HENCE my need to enter two digits and concatenate them so i can pass them through a switch statement.
