HP 17bII manual Exiting Menus e, Clearing Values in Menus, 28 1 Getting Started

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: egets 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 sbefore the menu key

†To store the same number into two different variables, use sfor the second variable, e.g. 25 *s )
