Attaching a Formula to a List Name
You can attach a formula to a list name so that the formula generates a list that is stored
and dynamically updated in the list name.
♦
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.
To attach a formula to a list name on the home screen or in the program editor, the syntax is:
Form(" formula ", listName )
When you enter a new list name as the second argument for Form( , the list name is created
and stored in the LIST NAMES menu and VARS LIST screen upon execution.
ᕡ Store elements to a list name.
ᕢ Select Form from the LIST OPS menu;
Form( is pasted to the cursor location.

ᕣ Enter a formula in quotation marks.

which you want to attach the formula.

You cannot edit an element
of a list created from an
attached formula unless you
first detach the formula from
the list name.
When you include more than
one list name in an attached
formula, each list must have
the same dimension.
Begin these steps on a blank
line on the home screen.
To view a formula attached to
a list name, use the list editor
(page 157).
