No, this is completely wrong, there is a very important semantic
difference between passing a parameter as IN OUT (which in Ada
is often free to pass by copy or by reference), and passing a
pointer by value. You should definitely read up on this in
standard books on programming languages, the difference is
pretty substantial semantically :-)
