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.
