The Real mode is the mode for real numbers. This mode is the mode we usually work in. It does not display complex values unless complex numbers are entered in as input. Calculators are initially set in the Real mode, but once people start getting into the tail end of Algebra they'll mostly likely put their calculators into the a+b

If you want to use shading with points, lines, or circles you will have to set the window variables because they use the coordinate plane. However, if you are using shading with functions, you may have to use different window variable settings. To find Shade(, press and [DRAW]. Scroll down to

Shells act like a Windows for the calculator and are made using Assembly language. They display all compatible games in a list, so you can easily choose which game or program you'd like to play. They also display how much memory you have left and how big the program you've highlighted is. The three shells that I'll discuss are AShell (the one I mainly use), SOS (I've tried once and very similar to AShell), and TI-Explorer (I have never used this before and just recently heard of it). You can make any BASIC program compatible for these assembly shells by putting a : (colon) at the beginning of your program.

- Ashell only works for the TI-83. To download it, click here.
- SOS also only works for the TI-83. To download it, click here.
- TI-Explorer is a powerful shell, which works for only the TI-83 and on the screen looks a lot like Windows Explorer. The good thing about this shell is that it runs AShell, SOS, and Ion programs. To download it, click here.
- Ion is the newest of the assembly shells and works for both th TI-83 and TI-83 Plus. Games that are Ion-compatible are the only games that can work with either the TI-83 or TI-83 Plus. AShell- or SOS-compatible games will not work on TI-83 Pluses. To download it for TI-83, click here. For the TI-83 Plus, click here.

The TI-Graph Link Cable connects your calculator with your computer so that you can send downloaded programs from your computer to your calculator.

The four window variables that are neccessary to change to make points, lines, and circles compatible with graph screen text are: Xmin, Xmax, Ymin, and Ymax. The text will still display if these window variables are not set to what I suggest, but it is easier to align the text with lines, points, and circles with the variables set to what I suggest. There are other window variables such as Xscl, Yscl, and Xres, but they do not affect how the size of the screen. Those three variables are for when you're actually graphing something. To make points, lines, and circles compatible with your text, set the four varibles like this: 0Xmin, 94Xmax, 0Ymax, and -62Ymin. Xmin must be less then Xmax and Ymin must be less than Ymax in order for it to work. You can find all of the window variables by pressing , , and then scrolling down to whichever variable you want.
