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.
For example, the first screen below shows that elements
are stored to L3, and the formula L3+10 is attached to the
list name ÙADD10. The quotation marks designate the
formula to be attached to ÙADD10. Each element of ÙADD10
is the sum of an element in L3 and 10.
The next screen shows another list, L4. The elements of L4
are the sum of the same formula that is attached to L3.
However, quotation marks are not entered, so the formula
is not attached to L4.
On the next line, L6!L3(1):L3 changes the first element in L3
to L6, and then redisplays L3.
The last screen shows that editing L3 updated ÙADD10, but
did not change L4. This is because the formula L3+10 is
attached to ÙADD10, but it is not attached to L4.
Note: To view a formula that is attached to a list name, use the stat list
editor (Chapter 12).
