As New_Page suggests, this is a printer-like command. The funny character
you are seeing is called the 'form-feed' code, instructing the printer
to move to the next page.
On some consoles, sending a form-feed will actually clear the screen,
on others it will simply display the character. On Win95 (if that is
what you are using) the latter is the case.
A very simple solution is:
Num_Rows : constant := 25; -- number of screen rows;
procedure Clear_Screen is
begin
for I in 1 .. Num_Rows loop
New_Line;
end loop;
end Clear_Screen;
