Archiving Variables (Archive, Unarchive)
You can store variables in the TI-84PlusCE user data archive, a protected
area of memory separate from RAM. The user data archive lets you:
• Store data, programs, applications or any other variables to a safe location
where they cannot be edited or deleted inadvertently.
• Create additional free RAM by archiving variables.
By archiving variables that you do not need to edit frequently, you can free up
RAM for applications that may require additional memory.
The graphing calculator places an asterisk (ä)to the left of archived variables.
You cannot edit or execute archived variables. You can only see and
unarchive them.
Example:
If you archive a list named L1, you will see that it exists in memory. However, if
you select and paste the name L1 to the home screen, it will not appear on the
home screen. You must unarchive it in order to see its contents and edit it.
Note: Image Vars are run and stored in archive, but when an Image Vars
displays in VARS 4:Picture & Background, the BACKGROUND menu does not
display the asterisk ä.
