Yes.
Ciao, Michael.
Ok, but I've another question related to this.
Suppose this is the superclass chain --
A -> B -> C -> D -> E -> F -> G
Then for D, the superclass chain is A -> B -> C, and in this chain D is
the most subordinate.
For F, the superclass chain is A -> B -> C -> D -> E and here too F is
the most subordinate.
So what do you mean by the 'superclass chain'? The whole chain A to G or
is it relative to a particular object class (because each object class
at a different level will have a different superclass chain).
