Hi!
i read what you wrote, and i read what other ppl wrote, and there is a VERy
simple way to do it, in fact two ways.
1. declare the object:
    class Object;

    typedef *Object Objpoint; /* i think thats how typdef go, long time i havnt
used it :) */

  class object
{
.
.
.
    Objpoint ptr;
}
thats way one. way two, i can remember from old pascal compilers, when u wanted
to create chained lists,
you declared the pointer just before the class, and the compiler 'knew' to go
the class just afterwards.
thats how it went in the old days.

btw!! i forget, i can also declare the pointer void * !!!
