It's more polite to put the real subject in the subject line. A lot of
us just ignore articles that only say "Please help!". You caught me at
the end of the day, when I don't have the energy for real work :-)

See Text_IO.Get_Immediate. This is supposed to not wait for the <CR>,
but it depends on whether your compiler does this or not. The latest
version of GNAT does, at least for some platforms. (It is also polite to
say what platform you are using, and what version of what compiler).

I can't help you there, but there are some packages that have been
written to do this. Start at the Ada home web page:

http://www.adahome.com/

and look around for resources and/or source code libraries. You'll find
it, and lots of other good stuff, to.

This is NOT an effective threat; it's easy to ignore annoying posts
(just skip any subject line that is not meaningfull !-)
