Pardon me, but can you give me the C-language statement that sets the
color of a charactor on the screen? I'm doing C for 20 years and never
heard about that feature of the language;-) But perhaps you mean that
for C or other languages their exist conveniant libraries to do that.

IMHO even in C you hardly find a library that does that kind of
thing in an OS independent way. On most UNIXes and similar OS
you'll find a library called curses (or ncurses on free OSes) which
deals with screen manipulation in a terminal independent way.
If you look into the sources of ncurses
(ftp://ftp.gnu.org/pub/gnu/ncurses)
you'll find there a quite complete Ada95 binding for this library.
Modern curses implementations (lile ncurses) support also colors.
The Ada95 binding for ncurses as BSD style license, so you are
quite free to use it for whatever you want.
