Where does the mojo process occur?

I tried running this program and got unexpected results. I'm new to these forums, so I don't know if the (code) and (/code) tags work like they do on the Blitz Basic website.
Import mojo

Function Main:Int()

	Local thegame:Game = New Game
	thegame = Null
	If thegame = Null
		Print "Mojo is gone."
		Print "Mojo is still there."
	Return 0

End Function

Class Game Extends App

	Method OnCreate()
	End Method
	Method OnUpdate()
		Print "Mojo is working somewhere."
	End Method
	Method OnRender()
	End Method

End Class

Running this program will print that Mojo is gone, but it is still running in the background because it keeps printing "Mojo is working somewhere" even though it has been dereferenced.

I assume that creating a new instance of Game turns the code over to the OS and Monkey has no control over it from there, but I'm not sure if this is correct. Can anyone shed some light on this?

Excellent! The (code) and (/code) tags do work. That helps a lot.

look at the generated code and you will get an idea of whats going on.

basically when an instance is created the super new(from the App) is executed and is what's controlling the processes(looping).

So I take it that there is no way to stop an instance of Mojo once it's running, other than to close the program? The reason why I ask is because I am trying to set up a framework for a larger project, and I am trying to decide on the best way to handle multiple levels. It looks like I will need to set up all of my code inside the one instance of Mojo and have the program run specific sections of code based on what level the user is currently playing. This is a little different than what I am used to, but it will work nonetheless.

Thanks for the response!

i was also surprised that Main is "useless", because it run out.
I thought first that it is executed at app end

Yeah, as I am playing around with the code, it's starting to make more sense. Basically, the Main() is there just to create Mojo, and then it serves no purpose for the rest of the program. I had tried to set up an infinite loop in the main that would execute certain sections of code based on a variable which describes the current level, but it always caused the program to hang. Instead of setting up a loop in the main, I just set up the appropriate code inside the instance of "Game" and it achieves the same effect. This is a better approach than my old techniques because I don't have to reload Mojo every time I change levels.

(you can also write commandline tools inside Main() without the need of mojo using the C++_Tool target)

Yes, if you want to generate a list of prime numbers or something you can do it just fine in Main().
