This program typically sets up the aplet's initial configuration. The START option on the menu is also useful for resetting the aplet. Command syntax The syntax for the command is as follows: SETVIEWS "Prompt1";"ProgramName1";ViewNumber1; "Prompt2";"ProgramName2";ViewNumber2: (You can repeat as many Prompt/ProgramName/ ViewNumber trios of arguments as you like.) Within each Prompt/ProgramName/ViewNumber trio, you separate each item with a semi-colon. Prompt Prompt is the text that is displayed for the corresponding entry in the Views menu. Enclose the prompt text in double quotes. Associating programs with your aplet If Prompt consists of a single space, then no entry appears in the view menu. The program specified in the ProgramName item is associated with the aplet and transferred whenever the aplet is transmitted. Typically, you do this if you want to transfer the Setviews program with the aplet, or you want to transfer a sub-program that other menu programs use. Auto-run programs If the Prompt item is "Start", then the ProgramName program runs whenever you start the aplet. This is useful for setting up a program to configure the aplet. Users can select the Start item from the VIEWS menu to reset the aplet if they change configurations. You can also define a menu item called "Reset" which is auto-run if the user chooses the button in the APLET view. 21-15

Programming
21-15
options use, or the program that defines the aplet’s
VIEWS menu.
You can include a “Start” option in the VIEWS menu
to specify a program that you want to run
automatically when the aplet starts. This program
typically sets up the aplet’s initial configuration. The
START option on the menu is also useful for resetting
the aplet.
Command syntax
The syntax for the command is as follows:
SETVIEWS
"
Prompt1
"
;
"
ProgramName1
"
;
ViewNumber1
;
"
Prompt2
"
;
"
ProgramName2
"
;
ViewNumber2
:
(You can repeat as many
Prompt/ProgramName/
ViewNumber
trios of arguments as you like.)
Within each
Prompt/ProgramName/ViewNumber
trio,
you separate each item with a semi-colon.
Prompt
Prompt
is the text that is displayed for the corresponding
entry in the Views menu. Enclose the prompt text in
double quotes.
Associating programs with your aplet
If
Prompt
consists of a single space, then no entry appears
in the view menu. The program specified in the
ProgramName
item is associated with the aplet and
transferred whenever the aplet is transmitted. Typically,
you do this if you want to transfer the Setviews program
with the aplet, or you want to transfer a sub-program that
other menu programs use.
Auto-run programs
If the
Prompt
item is “Start”, then the
ProgramName
program runs whenever you start the aplet. This is useful
for setting up a program to configure the aplet. Users can
select the Start item from the VIEWS menu to reset the
aplet if they change configurations.
You can also define a menu item called “Reset” which is
auto-run if the user chooses the
button in the APLET
view.
