Part 4 of a 4-part series.
Using the Casio Prizm graphing calculator, we will write a program to create a basic text editor on the calculator. Users of the fx-9750GII and fx-9860GII calculators will be able to write the same program commands on those units. This program will teach the proper syntax to use for the GetKey command and various string manipulation commands in Casio's user-level programming language.
