Use
ClrAllLists
(Chapter 18). All elements of all lists in
memory are cleared, all formulas are detached from all
list names, and all lock symbols disappear. All list
names remain.
As described above, one way to detach a formula from a
list name is to edit an element of the list to which the
formula is attached. The TI
-
83 protects against
inadvertently detaching the formula from the list name by
editing an element of the formula-generated list.
Because of the protection feature, you must press
Í
before you can edit an element of a formula-generated list.
The protection feature does not allow you to delete an
element of a list to which a formula is attached. To delete
an element of a list to which a formula is attached, you
must first detach the formula in any of the ways described
above.
