Programming commands

This section describes the commands for programming with HP 39G/40G. You can enter these commands in your program by typing them or by accessing them from the Commands menu.

Aplet commands

These commands control aplets.

CHECK	Checks (selects) the corresponding function in the current
	aplet. For example, Check 3 would check F3 if the current
	aplet is Function. Then a checkmark would appear next to F3
	in Symbolic view, F3 would be plotted in Plot view, and
	evaluated in Numeric view.
	CHECK n
SELECT	Selects the named aplet and makes it the current aplet. Note:
	Quotes are needed if the name contains spaces or other
	special characters.
	SELECT apletname
SETVIEWS	The SETVIEWS command is used to define entries in the
	VIEWS menu for aplets that you customize. See “About
	customizing an aplet” on page 15-9 for an example of using
	the SETVIEWS command.
	When you use the SETVIEWS command, the aplet’s standard
	VIEWS menu is deleted and the customized menu is used in
	its place. You only need to apply the command to an aplet
	once. The View menu changes remain unless you apply the
	command again.
	Typically, you develop a program that uses the SETVIEWS
	command only. The command contains a trio of arguments for
	each menu option to create, or program to attach. Keep the
	following points in mind when using this command:
	• The SETVIEWS command deletes an aplet’s standard
	Views menu options. If you want to use any of the
	standard options on your reconfigured VIEWS menu,
	you must include them in the configuration.
	• When you invoke the SETVIEWS command, the
	changes to an aplet’s VIEWS menu remain with the
	aplet. You need to invoke the command on the aplet
	again to change the VIEWS menu.
