Swap back to the Program Catalog, position the highlight on the program

.MSG.SV and the program. Apart from the screen going blank for a

moment nothing will appear to happen, but in fact the link to the normal

VIEWS menu which ‘Message’ inherited from its parent aplet Function has

been severed and a link to the new menu you built in .MSG.SV has been

substituted. Press VIEWS to check.

Providing that you have done everything correctly, this is now the end of the

process - the aplet is now ready to be run. In the APLET view, make sure the

highlight is still on the aplet and press or ENTER to run it. If you get an

error message at any time then you may have to and the

program.

When you do this, the aplet will run the

program .MSG.S which will display a

MSGBOX.

The line in the SETVIEWS command

controlling this was:

"Start";".MSG.S";7;

Since the triple ends with a view number of 7,

this means that after the program terminates

(when you press ), the VIEWS menu will

display again.

If you choose the option ‘Message 1’, then this

will cause the program .MSG.1 to be run,

displaying the screen on the right. This line in

the SETVIEWS command also terminated with

a view number of 7 so when you press

the VIEWS menu will display again.

The program line for this was:

MSGBOX "Hello world! 3+4 = "3+4:

Items in quotes are displayed as they appear, while expressions outside

them are evaluated before being displayed. Expressions can include

variables and calls to functions.
