calling all Mac users

[john massey]

The reason I am calling Mac users is because you can Copy from a post and Paste into TI Connect and download it into your 84. Then run it. My problem in the past had centered around understanding a problem and then explaining what is happening. There are three programs below.

//. this is the first on it is used to set up the testing of REDUE22. call it anything you choose

{1,3,5,7,9,11,13,15,16}→⌊OVER1
prgmREDUE22


// the next program must be named REDUE22. In this program you will see a problem. You must Decide on an answer and use the number keys to enter the correct answer and then press the "enter" key. Then the program has a pause for you to see what has happened so you must press the "enter" key again to go on to the next problem

// I have used this statement If J=3:STOP to look at what is happening in a certain location. There are certain locations where a simple stop will work but the If statement above will not work. I conclude that "J" does not exists in that location. Which makes no sense to me. Here is the code.
