To answer the other half of your question, the list implementation in your book appears to be a proper subset of the Strawman. So the answer to your question is really in this thread, where I was asked to add (or justify adding) all that extra stuff. :-) My guess is that your implementation was designed for instructional use, while Booch was degined for industrial use. The general idea of this process is that somewhere in between is perhaps a "sweet spot" that can be mostly acceptable for both uses. --- T.E.D. homepage - http://www.telepath.com/dennison/Ted/TED.html No trees were killed in the sending of this message.
