HP 12C Permutation and Combination

[Gamo]

Thanks Dieter !!!

Your code example of Permutation and Combination is excellent with user friendly way to just input 0 R/S or 1 R/S and the program is much smaller in steps too.

How about a Pricing Program that calculate the Price, Cost, Margin, and Mark Up
Since the HP 12C didn't have this feature and is a must have feature for a Financial Calculator. When you know the two variables and it will calculate the other two unknown variables. I did this on the Solve App on HP Prime and it work perfectly but I always wish I have this pricing feature for HP 12C

Thank You
