Is X and Ada a practical combination?  My organization's systems
are currently implemented using C and Sunwindows, but future projects
need to be done using Ada.
Sunwindows makes calls back to the application program which is no
problem when the application is in C, but if it is in Ada you need to
call Ada from C, something I don't know how to do. (vice versa is easy).

>From what little I've seen of the X toolkits, it appears that
X makes 'callbacks' to the application program. If X is in C
(which would be acceptable in our 'Ada' system) and the application
is in Ada, it looks like we still have the same problem.

Do we need to wait for an Ada implementation of X? Will such a thing
be available in my lifetime? Am I missing a more obvious solution?
