Attaching Formulas to List Names

Attaching a
Formula to a List
Name
You can attach a formula to a list name so that each list element
is a result of the formula. When executed, the attached formula
must resolve to a list.
When anything in the attached formula changes, the list to
which the formula is attached is updated automatically.
When you edit an element of a list that is referenced in the
formula, the corresponding element in the list to which the
formula is attached is updated.
When you edit the formula itself, all elements in the list to
which the formula is attached are updated.

stored to , and the formula
