protected objects and external call

[evangeli@cnam.fr (Evangelista Sami)]

hi all

in RM-9.5.1 we see there is a difference between external and internal
protected calls. Let's consider the following code
----------------------------------
protected type Prot is
   procedure P;
end Prot;
My_Prots : array (1..10) of Prot;

protected body Prot is

   procedure P is
   begin
      .....
      My_Prots(5).P;
      ....
   end;

end Prot;
----------------------------------

Is the call "My_Prots(5).P" always considered as an external call or
is it an internal call if the object on which is executed the
procedure is My_Prots(5) ?

Thanks for any help
