I think Albert's guess is indeed more likely to be correct. Assuming that
a beginner is using the DEC compiler is probably not realistic. But the
above code is convoluted, Use Ascii.ESC instead:

        Ada.Text_IO.Put (Ascii.ESC & "[2J");

or, if you are in a frightfully politically correct mode (Ascii.ESC is
another of those very useful Ada features which the designers put in
Annex J for no good reason), then you can add a context clause for
Ada.Characters.Latin_1 and use Ada.Characters.Latin_1.Esc instead of
Ascii.ESC (the latter is in practice far more convenient, since it
is shorter to write, and declard in Standard).
