Well surely you would never code a military real-time application in IDL
in the first place. A *prototype*, certainly. But the idea behind
prototypes is that once you're done with them, you throw them away. In
fact, you might even throw away two prototypes, e.g.

(1) Prototype V1 (IDL) demonstrates the user interface, to get feedback
from users (no functions)
(2) Prototype V2 (IDL) demonstrates basic functionality
(3) Realtime V1 (C++) is the first production version

Code re-use in this process might happen from steps (1) to (2), but it
probably would not happen from step (2) to step (3). The key information
that gets refined in this process is the application *design*. It is
perfectly appropriate to code the application at step (3) in whatever
language is appropriate. I'm just saying that you're probably wasting
your time if you try and 'translate' the code from step (2) for use in
step (3).

Cheers,
Liam.
