where they cannot be edited or deleted inadvertently. Archived variables are indicated by asterisks
(ä) to the left of the variable names. 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.
