To wow, and Jackie and tsuwm I just want say thank you. It is said that the esteem of one's peers is something to be valued. If that is so, then to be esteemed by those who are one's superiors must be even more precious. Newton may have stood on the shoulders of giants, but this little pygmy (emphatic, not tautological) is surrounded by them here, and is humbled that they should defend him as they did. Thanks again,
Max

p.s. tsuwm, did you know that Ænigma thinks you're a tub?
