if this is correct, then this is exactly what I do in most if not all
of my objects & behaviors. what has been confusing here, I think, are
the symantecs. all this talk of accessors not being allowed and no
Get/Set functions has been what has had me turned around. if you are
saying that you can get information from an object as long as you do
not modify it or get it directly and you can pass information to an
object, as long as what you are passing does not correspond to an
actual property of an object, then I definitely understand.

nope, I don't think that you miss the boat at all. now if we ge an
agreement from Jakob that this is correct, then I personally am home
free <grin>. the problem has been the statements in the Java article
about absolutely no accessor functions and if you need any you should
be including the accessing method in the object. or at least that is
the way I read the article.
