hello, this is a instructable explaining the basics of programming on your TI-83 84 calculator. Also, i could make other instructables on more specific things, depending on the feedback. Sorry about the pictures, i'm bad with a camera.
Step 1: Create your program
ok, first, you need to create your program. first hit the program button, then keep going to the right until you get to the new section as seen on the picture. name your program whatever you want, i named mine test. you should end up at this screen (picture 2).
Step 2: Begin the program
now you will start your program with a basic function. First, hit the program button then go one section to the right, near the bottom, beside the number 8, is an item called clrhome, select it. this will make the person using the program's home screen turn blank, so make sure you have nothing important there before starting the program. Anyway, hit enter to start a new line and hit program, then the second section, the the third one will be disp, this will allow you to display any text or numbers, after you insert a disp tag, type "HELLO" with the quotation marks, this means that after starting the program, it will display hello. So now your program will start, clear the screen, and say HELLO, but if you start, it will make the text then automatically end the program. to prevent this, we will put in a pause tag. the pause tag is found if you hit the program button, then scroll down to number 8 and there it is, as seen in the picture. Once you insert this tag, if you start your program, it will wait until you hit enter for it to be done.
Step 3: Test #1
Ok, so now it is time to test your program, first start on the home screen, go to programs and hit your program so it comes up like in the first picture, once you have that, hit enter, your screen should look like the second picture. And that is your current program!
