<<on a PC, I use the escape sequence:
Ada.Text_IO.Put (Character'Val(27) & "[2J");
Good luck.>>
This is the second person to write Character'Val(27) rather than the
much clearer Ascii.ESC! Generally you always want to reference control
characters by name rather than by mysterious constants. Actually better
style is
Clear_Screen : constant String := Ascii.ESC & "[2J";
...
Put_Line (Clear_Screen);
Naming constants is fundamental technique for making programs more
readable!
