Yes.  Ada supports threading (simultaneous subprocesses of a single
program).

The language element which enables threads is a TASK.  Ada also supports
IPC via a mechanism called RANDEVOUZ.

Each thread is an instance of a TASK TYPE.  Instances can be refrenced
like any
other variable (by their name, address etc.), including arrays of
threads, etc.
To pass information between threads, you can use RANDEVOUZs, which are
agreed
"meething places" where two threads can "meet" and "talk" (pass
information).

Depends on your debbuger and environment.  I know my debbuger (Verdix
SELF for
IBM RS6000, AIX) has to ability to set breakpoints at specific tasks,
and I think
that should be the case for any decent ADA debugger.

The infamous ADA LRM (which can be found online on the web as well), and
ofcourse
various books dealing with ADA.

                           Good luck with your FAQ,
