Here a quick way of clearing the screen on NT:

  function Command_Interpreter( Command : in Interfaces.C.Strings.Chars_Ptr )
                                return Interfaces.C.Int; 
  pragma import( c, Command_Interpreter, "system" );

  -- Set_Console_Mode: This function sets the number of lines and columns 

  procedure Set_Console_Mode is
    iResult : Interfaces.C.Int;
  begin
    iResult := Command_Interpreter( Interfaces.C.Strings.New_String( 
                          "MODE CON COLS=80 LINES=25" ) );
  end Set_Console_Mode;

  -- Clear_Screen: This function clears the screen 

  procedure Clear_Screen is
    iResult : Interfaces.C.Int;
  begin
    iResult := Command_Interpreter( Interfaces.C.Strings.New_String( "CLS" ) );
  end Clear_Screen;
