Strange! That is not syntax. There is just no such thing in Ada: 1. For any type T I declare, I must be able to define a constructor. This includes T'Class. 2. For controlled types Initialize is not a constructor because it is not always called and because it can be called explicitly out of place. And I must be able to provide parameters to constructors. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
