VL Referencing non-active drawings

[Olhado_]

I have been self teaching myself LISP, VL, and now VBA, for AutoCAD. Well when it comes to Visual LISP is there a way to "get" any properties or anything else from a drawing that is not the active drawing?

 

From my web searches it sounds like all work needs to be done in the active drawing. Is this correct?

 

A little background:

 

What I am trying to do is copy styles, layouts, and page setups from our dwt file, after importing a drawing into AutoCAD. I managed to do this by basically recreating the styles and using (command "-layer" ... ) and (command "-psetupin" ... ); but I was wondering if there is a more efficient way to do this and the only other way that seems feasible is with VL.

Since I know I can be wordy, I basically want to know if you can reference non-active drawings and if so how?

 

Thanks.
