Archiving and UnArchiving Variables
Archiving and UnArchiving Variables
Archiving allows you to store data, programs, or other variables to the
user data archive where they cannot be edited or deleted inadvertently.
Archiving also allows you to free up RAM for variables that may require
additional memory.
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.
Note: Not all variables may be archived. Not all archived variables may be
unarchived. For example, system variables including r, t, x, y, and
q cannot be
archived. Apps and Groups always exist in Flash ROM so there is no need to
archive them. Groups cannot be unarchived. However, you can ungroup or
delete them.
