and evaluated in Numeric view.

SETVIEWS
The SETVIEWS command is used to define entries in the
VIEWS menu for aplets that you customize. See
“Customizing an aplet” on page 16-9 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 VIEWS 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.
•
All the programs that are called from the VIEWS
menu are transferred when the aplet is transferred, for
example to another calculator or to a PC.
•
As part of the VIEWS menu configuration, you can
specify programs that you want transferred with the
aplet, but are not called as menu options. For
example, these can be sub-programs that menu
