Never mind, I got it working, stupid mistake in my testing.

yes just like that function. I just learned about absolute so I was making us of it. Seems to work the same as casting in FreeAndNil. Thanks for helping.

    procedure FreeAndNil(var obj);
      var
        temp: tobject;
      begin
        temp:=tobject(obj);
        pointer(obj):=nil;
        temp.free;
      end;
