Allow only letter inputs.

[mystycs]

How can i create a input that only allows the letters a b c d

The console will ask to please enter a letter. And they can only enter the letters a b c d.

And if they enter it, it says thank you for enter a, or b or c or d.

I'm sure I've seen someone else ask this question on here, I might be wrong! Please show that you have at least tried :P

I'll give you an idea:

initialise (char) c; 

do 
 -> input c 

 -> while (c IS NOT 'a', OR 'b', OR 'c')

 -> print "Yes I did it!!"
