When you say 'object' do you mean in the OO sense? Usually the OO community use 'object' to mean an identifiable state machine located at some address and don't regard the location to be part of its state. Furthermore usually the identity of an object is determined *only* by its location and has nothing at all to do with its current state. Received on Tue Jul 21 2009 - 11:04:34 CEST
