Notes about 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
(Chapter 7), and all
• From an editor, you can store to matrices, lists, and
• From the home screen, a program, or an editor, you can store a value to a matrix element or a
list element.
• You can use
DRAW STO
(Chapter 8).
• Although most variables can be archived, system variables including r, T, X, Y, and q cannot be
archived (Chapter 18)

Storing Variable Values

Storing Values in a Variable
Values are stored to and recalled from memory using variable names. When an expression
containing the name of a variable is evaluated, the value of the variable at that time is used.
To store a value to a variable from the home screen or a program using the ¿ key, begin on a
blank line and follow these steps.
1. Enter the value you want to store. The value can be an expression.
2. Press ¿. ! is copied to the cursor location.
