Because Total is a Positive of range 1 .. Integer'Last, so it can never be 0
(it will raise an exception and dying silently...)

Total : Integer := 1000;

exception
   when others =>
      Put_Line ("Oops!");
end Susan;

would have stopped it being silent.

Also, sharing Total between the tasks is poor, it should be a protected
object.

And finally, what's wrong with Put_Line (instead of Put/New_Line pairs)?

Cheers
