A message appears asking if you want to create a variable called YOU. Tap or press

to conrm your intention.

The variable YOU is created and contains the list {1,2,3}. You can now use that variable in subsequent

calculations: For example, YOU+60 will return {61,62,63}.

Working with app variables

Just as you can assign values to Home and user variables, you can assign values to app variables. You can

modify Home settings on the Home Settings screen ( ). But you can also modify a Home

setting from Home view by assigning a value to the variable that represents that setting. For example,

entering Base:=0 in Home view forces the Home settings eld Integer (for the integer base) to

binary. A value of 1 would force it to octal, 2 to decimal, and 3 to hex. Another example: you can change the

angle measure setting from radians to degrees by entering HAngle:=1 in Home view.

Entering HAngle:=0 forces the setting to return to radians.

You can see what value has been assigned to a variable—whether Home, app, or user—by entering its name

in Home view and pressing . You can enter the name letter by letter, or choose the variable from

the Variables menu by pressing .

More about the Vars menu

Besides the four variable menus, the Vars menu contains a toggle. If you want the value of a variable instead

of its name when you choose it from the

Vars menu, tap . A white dot will appear next to the menu

button label to indicate that it is active and that variable values rather than names will be returned upon

selection.

For the Home and app variables, use the Vars menu to get help on the purpose of any of these variables.

Select the variable of interest and press

. Suppose, for example, that you wanted to get help on the

Function app variable GridDots:

Press to open the Vars menu.
