I think that's a fairly reasonable parse of the phrase. Thus I expected to be able to combine other constants using the dot operator as Gary is trying to do. Obviously, it didn't work, and I removed the "base" constant and replicated its value in the other constants--a situation constants were designed to obviate. Gary, you'd probably be better off asking for the technical reason behind this limitation on a -devel list. :) -- David Harkness Senior Software Engineer High Gear Media, Inc.
