Using dedicated program functions

Redefining the View menu

There are nine dedicated program function names, as shown in the table below. These functions are called when the corresponding keys shown in the table are pressed. These functions are designed to be written into a program that controls an app and used in the context of that app.

Program	Name	Equivalent
		Keystrokes
Symb	Symbolic view	Y
SymbSetup	Symbolic Setup	SY
Plot	Plot view	P
PlotSetup	Plot Setup	SP
Num	Numeric view	M
NumSetup	Numeric Setup	SM
Info	Info view	SI
START	Starts an app
RESET	Resets or
	initializes an app

The View menu allows any app to define views in addition to the standard seven views shown in the table above. By default, each HP app has its own set of additional views contained in this menu. The VIEW command allows you to redefine these views to run programs you have created for an app. The syntax for the VIEW command is:

VIEW "text", function()

By adding VIEW "text", function() before the declaration of a function, you will override the list of views for the app. For example, if your app program defines three views—"SetSides", "RollDice" and "PlotResults"—when you press Vyou will see SetSides, RollDice, and PlotResults instead of the app’s default view list.
