TJ - Object Model Question

["Steve Dugas" <sjdugas@xxxx>]

Hi TJ,
 
I am studying Scripting and AB Object Model. Can you please 
tell me what constitutes a "document" in AmiBroker?
 
Also, in the Object Model, how does Document relate to 
Application? I would think that Application would be at the top of the 
hierarchy, but I notice also that Document has an Application property. Thanks 
very much!
 
Steve
