(please use the developer mailing-list for such questions...)

GB.NewArray() and GB.FreeArray() allows you to create dynamic C arrays 
whose allocation is managed by the interpreter. These arrays can grow 
automatically as needed (with GB.Add or GB.Insert), or shrink (with 
GB.Remove).

You use them when you need a array whose size is not static.

GB.Array.New creates a Gambas array object (Integer[], String[], and so 
on). You use it when you need to return a Gambas array from a property 
or a method.

Then you have two choices: either you create it and store it inside your 
object structure, or you create it only when you return from the 
property or method.
