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
.
