You can attach a formula to a list name in the stat list
editor, and then display and edit the calculated list
elements. When executed, the attached formula must
resolve to a list. Chapter 11 describes in detail the concept
of attaching formulas to list names.
To attach a formula to a list name that is stored in the stat
list editor, follow these steps.
1. Press … Í to display the stat list editor.
2. Press } to move the cursor to the top line.
3. Press | or ~, if necessary, to move the cursor onto the
list name to which you want to attach the formula.
Note: If a formula in quotation marks is displayed on the entry line,
then a formula is already attached to the list name. To edit the
formula, press Í, and then edit the formula.
4. Press ƒ [ã], enter the formula, and press ƒ [ã].
Note: If you do not use quotation marks, the TI-83 calculates and
displays the same initial list of answers, but does not attach the
formula for future calculations.
Note: Any user-created list name referenced in a formula must be
preceded by an Ù symbol (Chapter 11).
5. Press Í. The TI-83 calculates each list element and
stores it to the list name to which the formula is
attached. A lock symbol is displayed in the stat list
editor, next to the list name to which the formula is
attached.
