Archiving And Unarchiving A Variable - Texas Instruments TI-89 Titanium Short User Manual

Archiving and Unarchiving a Variable

To archive or unarchive one or more variables interactively, use the
screen. You can also perform these operations from the Home
VAR-LINK
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.
Additional free RAM can improve performance times for certain types of
calculations.
