Memory and Variable Management

707

If you paste a variable name that is not in the current folder, the variable’s pathname is
pasted.

Archiving and Unarchiving a Variable

To archive or unarchive one or more variables interactively, use the

VAR-LINK

screen.

You can also perform these operations from the Home screen or a program.

Why Would You Want to Archive a Variable?

The user data archive lets you:

•

Store data, programs, or any other variables to a safe location where they cannot be
edited or deleted inadvertently.

•

Create additional free RAM by archiving variables. For example:

You can archive variables that you need to access but do not need to edit or
change, or variables that you are not using currently but need to retain for future
use.

Note:

You cannot archive variables with reserved names or system variables.

If you acquire additional programs for your TI-89 Titanium, particularly if they are
large, you may need to create additional free RAM before you can install those
programs.
