Menus, Menu Items, and Assigning Values to Menu Items

Many of the calculator's functions are located within menus. A menu is a cat- alog which permits you to select an item from a list of options. To access a menu, press the key, or secondary-function, key combination for the menu in

which you wish to work. To exit a menu, press O. For example, to access the Bond menu, press B. Once opened, you can scroll through the items in the menu by pressing <or >repeatedly. When you arrive at the last item in a menu, pressing <returns you to the first item. Similarly, pressing

>once on the first menu item scrolls to the last item in the menu. Some

menus have sub-menus. If an item represents a sub-menu, pressing I with that menu item displayed opens the sub-menu.

Most menu items consist of two parts: a name and an associated number. For example, the Fixed item in the Break-even menu is displayed in Figure 3.

Figure 3

The large (=) annunciator shows that the value assigned to Fixed is 120,000. If you perform a calculation with this item displayed by pressing

1+2=for example, Fixed is still selected as the current item, but the large (=) annunciator is now turned off, indicating the 3 is not the value assigned to Fixed. See: Figure 4.
