I participated in building a F16 radar simulator using no OS, C, & TMS320C30 processors running in parallel. We had a good team willing to listen to those of us with extensive realtime experience. The result was a system that could run essentially 24/7. Ok, so this thing will never really fly nor kill anyone if it fails, but the fact is one can craft C code that doesn't fail. I also participated in an ADA based project that had a small team of "insiders" who wouldn't listen to "outsiders" & the result was worse code & less reliability. This *was* a system meant to fly. Good coders can write good code regardless of language. Language won't make marginal coders, marginal coding teams, or bad design any better. -- <> Robert Geer & Donna Tomky | |||| We sure |||| <> <> bgeer@xmission.com | == == find it == == <> <> dtomky@xmission.com | == == enchanting == == <> <> Albuquerque, NM USA | |||| here! |||| <>
