Re: Constructor for a class with a task defined

["Rego, P." <pvrego@gmail.com>]

I tried all the suggestions (thanks to all!), but the ones which uses "<>" I got the message box when I included other constructor subclasses inside Small_Class (but worked pretty well in the simpler version):
raised TYPES.UNRECOVERABLE_ERROR : comperr.adb:423
gnatmake: "D:\src\mypkg.adb" compilation error

The one suggested by Simon worked as well too (and it was which I choose to use), but maybe a basic question: what is the difference between using the direct access approach in a local procedure and using the _P approach? I mean, before I had tried to use

   function Construct return access Small_Class is
      B : access Small_Class := new Small_Class;
   begin
      return B;
   end Construct;

and got the message "cannot convert local pointer to non-local access type"

so why does the (type Small_Class_Acc is access all Small_Class;) code 

   function Construct return access Small_Class is
      B : Small_Class_Acc := new Small_Class;
   begin
      return B;
   end Construct;

works? Should not it get me the same msg?
