Is there > anything obvious I'm missing? Well, I can't really recommend without seeing what you did (did you remember the preceding "&" for the type struct? Otherwise, I'd have to recommend Objects/unicodeobject.c in the Python source as a reference for how to do this. I've had a couple of questions about how to implement new types that I posted to the list, and never got much help, so I started using the Python source as a reference. I've gotten most of what I needed to know from there. HTH -- Steve Juranich Tucson, AZ USA -- http://mail.python.org/mailman/listinfo/python-list
