# Menu Demo

This program demonstrates how to create a menu that will allow you to 
launch a task from a list. This allows you to avoid the long delay in 
launching a new program from the main Lejos menu.

Each task is defined in a class, which must be a subclass of `Program`. 
`Program` defines two methods:

* `GetTitle`: returns a string with the tasks title, to be displayed in the menu
* `Run`: the actual code to run when the task is selected

A simple example of this is the `Beep` class (see beep.quorum):

```quorum
use Libraries.Robots.Lego.Sound

class Beep is Program

    public action GetTitle returns text
        return "Beep"
    end

    public action Run
        Sound sound

        sound:BeepSequenceUp()
    end

end
```

Once you have created a class for your task, create an instance of it and add it
to the menu in `Main:Main` (in main.quorum):

```quorum
        Beep beep

        menu:Add(beep)
```

When you run the program, you will see a list of all tasks that you added to the
menu. Use the up and down buttons to select the one you want to run, then press
the center button to run it. To ensure reliability, ensure a long, firm press of
each button. When you are done, press the back button to return to the Lejos
menu.
