John,
You posted this awhile back and it intrigued me but I never got a chance to check on it until now.

The property are still an array property but it is being masked by the COM barrier. To prove it is an array, try putting o.AnArray[2,1] in the Locals window and a value should be returned.

Attempting to view the array directly or use VFP array functions against it outside of the COM wrapper will fail.

Some tips:
1. Since Alen() won't work, add a property to your class (e.g. ArrLength) and a corresponding _Access method. In the _Access method, simply issue a return alen(THIS.AnArray). Then you can use it in your for xx = 1 to o.ArrLength statements.
2. If you want the array in a VFP friendly way, add a CopyData method. Pass in an object with an array property and use Acopy() to copy the object's array values to the objects. You won't have to return anything because you are passing the object parameter by reference.

HTH.
