Chapter 11: Lists 170
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, L
6!L3(1):L3 changes the first element in L3 to L6, and then redisplays L3.
Note: Use
Ì for negation (as shown in the example), not subtraction ¹.
• 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).
