There is a free file comparison utility called ExamDiff. It's very handy for figuring out what things in the Poser interface do at script level. For example save a pz3 (scene) with Chain Break off, then turn Chain Break on for one actor and save another pz3. Compair them in ExamDiff to see what changes Poser made to the code.
