Keys in price of typewriter. Net cost of typewriter. Keys in list price of chair. Net cost of chair. That's all there is to creating and running simple programs! But if you want to use programs frequently, you'll want to know more about programming - such as how to check what keystrokes are stored in program memory, how many keystrokes can be stored in program memory, how to correct or otherwise modify programs, how to skip keystrokes when running a program, and so on. Before you can understand these aspects of programming, we need to briefly discuss how keystrokes are treated by the calculator when they are stored in Program mode and when they are executed in Run mode.
