RE: Why understanding the call stack depth is important

["Metz, Zak" <Zak_Metz@xxxxxx>]

Surprisingly, I've never had a need to understand it beyond activation group 
scoping. I've never done any sending of messages up the stack, either. It's a 
big world inside that black box! It's nice not having to know all that to get 
it to work. But I do appreciate your helping me understand why that was a 
viable question.

Excellent point, Buck.  And it becomes even more important when dealing with
activation groups!
