That's what I've found. Ada is great for this, if you are somewhat
careful about portability while you are writing it. We managed to port
the entire current development baseline of our flight simulator
(including a frequency-based scheduler) from vxWorks/GreenHills to
NT/Gnat in a couple of hours. The only OS call in the whole application
so far is a call to set the RT-clock's frequency (we stub that out on
NT, since its not realtime anyway). The rest of the sim compiles on both
platforms with *no* changes.

I don't think this feat would be possible in any other language.
