Not exactly.

I want to view C2 as a C1 class object but when i invoque "datos" it
will be execuete the method defined in C2.
The problem is the point of view. I want to view like in java or other
OO language but IDL cant accept this point of view :(

With PERSON, MAN and WOMAN is more clear. I want to view a MAN or a
WOMAN only as a PERSON, something like a cast. Later when i execute
methods over this PERSON it will execute the "datos" method of WOMEN or
MAN depending of its subtype (that's polymorphism).
But i supossed this point of view is not possible in IDL.

My solution is to use an OBJ_ARR, put objects WOMAN and MAN in it and
consider that all are objects PERSON, then execute "datos" method on
every object of the array.

Thanks anyway for your time.
