An
Introduction to TI-83 Programming
Topics:
Getting
Started
- Turn your graphing calculator
ON.
- Click on the PRGM
(program) button.
- If you are starting a new program,
use the arrow keys to highlight NEW
and press ENTER. If you wish to edit an
existing program, use the arrow keys to highlight EDIT
and press ENTER. (I wouldn't
recommend editing programs until you are familiar with programming...
in other words, it's wise to learn by creating a new program from scratch).
- Type in the name of your new program.
It cannot exceed more than 8 characters and if you want to include numbers,
just press the ALPHA key to switch between number
input and alphabet input.
- Now you are ready to input the
code for your program.

How
to Run a Program
- Turn your graphing calculator
ON.
- Click on the PRGM
(program) button.
- Make sure the word EXEC
is highlighted at the top. Then, using your arrow keys, select the name
of the program you wish to run (execute) and press
ENTER. You may also press
the number of the appropriate program to execute it as well.

Commands
When programming your graphing
calculator program, you need to input commands. An
example of a command is:
Disp
"HELLO WORLD"
This line of code tells your graphing
calculator to write the text: HELLO WORLD when you run the program. The part highlighted
in bold red in the sample above is the command that you
need to select from a menu. You cannot type it. Rather, you must select
it from a menu. Notice that all the commands that you cannot type are
in lower-case letters while the text you type can only be typed in CAPITAL
letters.

Selecting
a Command
To select a command, you must first
have the code screen in front of you (follow the steps under Getting
Started). When the cursor is blinking, press the PRGM
button. You will see at the top:
CTL
I/O EXEC
Below these letters, you will see
a numbered list of commands you can choose. Try moving your arrow keys
to select any command and press ENTER (you may also press the appropriate
list number of the command you want and press ENTER).
You will see that menu disappear and the command you selected appear
on the code line. You have just selected a command. Table 1 shows the
commands available when you press the PRGM
key.

This section will list your programs.
If you select a program from this list, you are telling the calculator
to run the selected program in the middle of your program. |
These are the special
commands that you only use when creating a program. However, you can
use any command that you can normally use on your calculator in your
program. For example, if you want your program to display the cosine
of 7, just select the Disp
command press COS and
7 as usual.
