Hi everyone. Several weeks ago I indicated I was working on a "flame" r.e. NASA Mars Projects. I have finally finished it. It became somewhat lengthy. I generally try to avoid sending such lengthy messages via email, especially via a list server. I have put it on the web at an unpublished URL: www.caresscorp.com/Oliver.Academy/scky.sftwr.at.NASA.htm I will appreciate any feedback, even if you are in violent disagreement with anything I have to say. sro S. Ron Oliver, semi-retired professor of Computer Science and Computer Engineering. www.csc.calpoly.edu/~sroliver Tired of sucky software! ? Check out www.caressCorp.com and follow the links to software sucks and The Oliver Academy.
