You can solve your problem by using the curses library provided with almost
any UNIX like system. The curses library is a set of C routines allowing to
program your screen in a terminal independent way. If you think this is the
right way to go you may pick up the just released free software implementation
of curses named "ncurses" from ftp://prep.ai.mit.edu/pub/gnu. The nice thing
with ncurses is, that it comes with a complete Ada95 binding tested and
developed for GNAT.
