And I say that as someone who designed a distributed system that had client and server sides and had to make that work across versions from last week to 10-20 years ago. I took it more as "Be more and more careful what you say, get that more correct with each release, but tolerate the less correct stuff you might get from earlier versions". In no way did I think he meant ``make a "reasonable" guess when receiving garbage''. Garbage is garbage, you error on that. -- --- Larry McVoy Retired to fishing http://www.mcvoy.com/lm/boat
