Note: Only use this tutorial if you have a TI 83 or 84 series calculator

The first thing that I will teach you is how to create a program on your calculator.

Hit the button on your calculator that says PRGM and hit the left arrow once, your screen should look like this:

Hit enter to start making your program

You will have to enter a name for your program, for this time, we will call it OUTPUT, hit enter when you type it in.

In this program we will make it simply display HELLO WORLD on the screen

There are two simple commands to use to output words on the screen. Disp, and Output(, another command we will use is ClrHome

In this lesson all of the commands can be found by pressing the PRGM button then the right arrow so that you are in the I/O section of commands

Disp: will display the text on the top line, can be found in I/O number 3

Output(: Lets you choose where you want the text to appear, found in I/O number 6

ClrHome: clears everything off the screen, found in I/O number 8

Now to start our program.

I will type out the program and explain each line after the “//” as I write it.

• :ClrHome // We want to make sure the screen is blank when we start the program
• isp “HELLO WORLD” // This will display the words HELLO WORLD on the screen.

Now quit out of the program editor and go into your programs list and select OUTPUT.

Run it, it should look like this:

If it doesn’t, go back a retry until it does. If it did, congratulations, you just made your first program.

Note: If at any time you cant find a command, hit [2nd], [0] to access the list of all commands and scroll until you find it.

Now create another program called OUTPUT2

In this program we will use the output( command. To use this you need to split the screen into 8 rows and 16 columns. to display text, you will put output(row number, column number, Text). So to put an A at row 5, column 10, it would be Output(5,10,”A”)

• :ClrHome // Same reason as the first program
• :Output(4,1,”HELLO WORLD”) // This will display HELLO WORLD row 4, column 1

Quit out of the program and run it, it should look like:

Now you know everything you need to know about outputting text on the screen. Look here for future tutorials.
