The designers of Ada have always been very careful not hooking the
language into a specific system (for Ada83 even too minimalist, e.g.
the missing math libraries). You terminal issue is a good example
of the pertinence of this carefulness: in 1983 the terminals had
perhaps the "set cursor position" feature, but a normal command
line window in 2003 provide basically not more functionality than
what you find in Ada.Text_IO.
