After trying to add os_calls and found it was not portable between
Linux and Windows, I decided to try and forget about OS calls.
And ada program is an entity on its own and I was thinking how to
interact with other programs when not using os_calls or
ada.command_line.

All ada systems have the package Text_IO in common.
So the only way a program can comunicate to other programs is
about reading and writing each others files.

Just to see if the concept is usable I wrote
http://www.noam.nl/download/ada95/my_os.zip
and this makes me confident there is a way to have simultanious
programs running and interfacing without the need of being os
specific.

Noam.
