HP 12C Permutation and Combination

[Gamo]

I always wish that HP 12C include Permutation and Combination functions since this functions is a must have feature for a Financial Calculator. So I make a very simple program that combine both together. To use it just start at GTO 00 for Permutation and GTO 10 for Combination. Very easy to remember to start at GTO 10 for Combination. Simple and useful and here is the program.
