Exactly..What I was hinting at here is two separate things.
The first being that you could run Ada apps on a Rt Kernel (for the non real
time
stuff)..The second being that I think it would not be too tough to either
build
or use the exising GNAT linux in a no tasking mode tied directly into the
kernel
(sort of the way a C programmer would do it).

Depending on your problem, it may be that only a small portion is really
Real-time
and thus the need for tasking might be overkill..
Having said all of that the only reason I would even recommend it of course
is
that at the moment, it is the only freely available approach I am aware of.
