So I've been making a cool system for an Arma type server my friends and I are starting, one of the things we're using is Pocket Computers from ComputerCraft so I have just been putting a menu interface that basically connects all these programs you would use to help during the game. One of the programs I have is a calculator, I didn't make it because I've had trouble with them in the past but I was wondering if anybody had already written a program for pocket computers specifically that is a calculator that you can click the buttons rather than type the equation? Like something you would see on a phone. My experience with writing programs for both button clicking and calculators has lead to nothing haha so I was wondering if someone could help me out with that?
