Many menus in this calculator work like the example above. The rules
for using variables are:
! To store a value, key in the number and press the menu key.
∗†
Arithmetic calculations, as well as single values, can be stored.
! To calculate a value, press the menu key without first keying in a
number. The calculator displays
7197491:;<=>
when a value is
being calculated.
! To verify a stored value, press
R
(recall) followed by the menu
key. For example,
R
)
displays the value stored in COST.
! To transfer a value to another menu, do nothing if it is displayed
(that is, it is in the calculator line). A number in the calculator line
remains there when you switch menus. To transfer more than one
value from a menu, use storage registers. See page 45, “Storing and
Recalling Numbers.”
Exiting Menus (
e
)
The
e
key is used to leave the current menu and go back to the
previously displayed menu (as shown in the previous example). This is
true for menus you might pick by accident, too:
e
gets you out.
Clearing Values in Menus
The
@c
key is a powerful feature to clear all the data in the
currently displayed menu, giving you a clean slate for new calculations.
! If the current menu has variables (that is, if the display shows menu
labels for variables, such as COST, PRICE, and M%C in the MU%C
menu), pressing
@c
clears the values of those variables to
zero.

If you have just switched menus and want to store the result already in the
calculator line, then you should press
s
before the menu key
†
To store the same number into two different variables, use s for the second
variable, e.g. 25
