Archiving Variables (Archive, Unarchive)
You can archive data, programs, or other variables in a section of memory called user data archive
where they cannot be edited or deleted inadvertently. These archived variables are indicated by
asterisks (ä) to the left of the variable names. These archived variables cannot be edited or executed.
They can only be seen and unarchived. For example, if you archive list L1, you will see that L1 exists in
memory but if you select it and paste the name L1 to the home screen, you won’t be able to see its
contents or edit it until it is unarchived.
Note: Image Vars are run and stored in archive, but when Image Vars are displayed in the VARS
4:Picture & Background, the BACKGROUND menu does not display the asterisk ä.
Recalling Variable Values

To recall and copy variable contents to the current cursor location, follow these steps. To leave RCL,

• Press  |, and then select the name of the program (in the program editor only).
The variable name you selected is displayed on the bottom line and the cursor disappears.
3. Press Í. The variable contents are inserted where the cursor was located before you began
these steps.
Note: You can edit the characters pasted to the expression without affecting the value in memory.
