To create a new dynamically allocated array and initialize it with the
result from Array_Filter use:

  N := new Arr'( Array_Filter( A ) );

Also, since you say you're new to Ada, I'll also mention that this is an
unusual way of doing things in Ada.  A more common approach is to use
something like:

  declare
    Filtered_Data : Arr := Array_Filter( A );
  begin
    -- Do stuff with Filtered_Data here
  end;

Which avoids dynamic allocation on the heap altogether.
