4. More Variables: Single Value Variables and
LIST Variables
Additional single value variables (from A to Z, and θ) may be accessed. In addition, six
LIST variables (from L1 to L6) are readily accessible through the second function of
the Advanced Keyboard.
To save a list of numbers, follow the procedure below:
1.
On the Calculation screen (# ), create a list of numbers (“1,
2, 3”, in this example). Separate numbers with a comma
(,), and group the numbers with braces ({ and }).
2. Press R, then select
one of the six LIST variables.
To store the list in “L1”, press
@ 1 to call up the
LIST variable.
3. Pressing E will store the
list in the LIST variable. Note
that this procedure will
overwrite the list previously
stored in the LIST variable.
Refer to Chapter 9 “LIST Features” to learn more about how LIST
variables can be utilized.
