You can store variables in the TI-84 Plus CE Python 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 in most menus as well as in y L 2:Mem Management. You cannot edit or execute archived variables in CE OS Version 5.2 or earlier. In CE OS Version 5.3 and later, you can execute programs if they are stored in an archive. If needed, you can use the Archive/UnArchive commands to manage the memory location.
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.
