You can detach (clear) a formula from a list name in any of four
ways.
• In the stat list editor, move the cursor onto the name of the
list to which a formula is attached. Press Í
‘ Í. All list elements remain, but the formula is
detached and the lock symbol disappears.
• In the stat list editor, move the cursor onto an element of the
list to which a formula is attached. Press Í, edit the
element, and then press Í. The element changes, the
formula is detached, and the lock symbol disappears. All
other list elements remain.
• Use
ClrList (page 12.20). All elements of one or more
specified lists are cleared, each formula is detached, and each
lock symbol disappears. All list names remain.
• 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-82 STATS 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.
