Variables
On the TI.83 you can enter and use several types of data,
including real and complex numbers, matrices, lists,
functions, stat plots, graph databases, graph pictures, and
strings.
The TI.83 uses assigned names for variables and other
items saved in memory. For lists, you also can create your
own five-character names.

System variables
You can create as many list names as memory will allow
(Chapter 11).
Programs have user-defined names and share memory
with variables (Chapter 16).
From the home screen or from a program, you can store
to matrices (Chapter 10), lists (Chapter 11), strings
(Chapter 15), system variables such as

From an editor, you can store to matrices, lists, and
functions (Chapter 3).
