You can detach a formula in any of five ways.

♦ 

Use 

 to change the dimension of the list (page 159).

♦ 

Use value

 to store value to an attached-formula list element.

♦ 

Use 

, where listName is the attached-formula list.

♦ 

In the list editor, move the cursor onto the name of the attached-formula list, and then
press b : b. All list elements remain, but the formula is detached and the
lock symbol disappears.

♦ 

In the list editor, move the cursor onto an element of the attached-formula list. Press

b, edit the element, and then press b. The element changes, the formula is
detached, and the lock symbol disappears. All other list elements remain.

As described above, one way to detach a formula from a list name is to edit an element of
the attached-formula list. The TI

-86 protects against inadvertently detaching the formula

from the list name when you move the cursor onto one of the elements.

Because of the protection feature, you must press b before you can edit an element of
an attached-formula list. The protection feature prevents you from deleting an element of an
attached-formula list. To delete an element of a attached-formula list, you must first detach
the formula in any of the ways described above.
