An application object is generally used to package a set of properties and methods that will be used on an application wide basis; therefore, you would create it before any other functions attempted to access it, usually before your main READ EVENTS loop.

So that your application object does not go out of scope (by accident or due to an error), you would normally assign it to a PUBLIC variable or attach it to the _SCREEN object.

The beauty of the application object is that even if you created it initially in the "wrong" place, you can easily move the CREATEOBJECT/NEWOBJECT statement vs having to cut, copy and paste a whole bunch of "non-object" variable declarations and assignments.
