Chapter 11: Lists 166
On the next line, L
6!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).

Note: When you include more than one list name in a formula, each list must have the same
dimension.
