Phil, I found your answer in Lippman's book (p.179). I would have thought that my friend declaration was ok, because all the line friend void Matrix::trans( const Vector& v1 ) ; says is "function 'trans' belonging to class 'Matrix' is granted access to 'Vector's private members". No knowledge of Matrix is required other than to give 'trans' access. That seems innocent enough, but I guess that's the way it is. Doesn't seem right, somehow… -Bob
