I didn't read all the mail's, and I am quite astonished how far and how many details can discussed. Like, What for program-language would have been the best, ..... It's good to know what's happen. I think more important, you built something new (very complex). You invest some billion to develop it. You built it (an ARIANE 5, put several sattelites). The price of it several hundred millions and you don't check as much as possible, make a 'very complete check', especially the software. The reason that the software wasn't checked: It was too 'expensive'?!?!. They forgot murphy's law, which always 'works'. I think you can't design a new car without testing it completely. We test 95% of the construction and after six month selling the new car a weel will fall of at 160km/h. Ok, there was a small problem in the construction-software some wrong values, due to some over- or underflows or whatever. The result, the company probhably will have to pay quite a lot and probhably to close ! -------------------------------------------------------- -DON'T TRUST YOURSELF, TRUST MURPHY'S LAW !!!! "If anything can go wrong, it will." -------------------------------------------------------- With this, have fun and continue the discussion about conversion from 64bit to 16bit values,etc..
