[SOLVED] Need Help on designing 4x3 matrix ALPHABETICAL KEYPAD using 8051

'b a b y' looks fine, I just extended your code, Its not actually looking professionally. If you want to make it as a keypad code you have to do lot of changes, because the keypad only occupies whole code.

But still it is possible to correct this mistakes easily, I will review your code when I have free time.
