proceed to correct the list, name the list, get another list, or do
statistical calculations.

Viewing and Correcting the List
To display a particular list, use  (see page 127).
The
[ and ] keys move up and down the list one number at a time.
@[ and @] display the beginning and end of the list.
Changing or Clearing a Number. To change a number after it’s been
entered: display the number, key in the new value, and press
I .
Use the same method to clear a number to zero. (Do not press
C or
< , which clears the calculator line.)
Inserting Numbers into a List. Insertion occurs before (or above) the
current entry. Pressing
 inserts a zero item and renumbers the rest
of the list. You can then enter a new value.
For example, if ITEM(6) is in the display, pressing
 puts a new,
zero item between the previously numbered ITEM(5) and ITEM(6).
