Jorge,

The amembers() function does create a real array. Don't confuse this array with the native collections.

I think help and docs label collections as arrays because you access it just like an array, but as you found collections don't work in functions like alen(). The Controls, Objects, DataEnvironment, Pages etc collections exist in the appropriate container classes.
