My assumption is that "kValueOpTypeCodePYTHONCALLBACK" is just a placeholder. Without further parameters, because they are set by the Python code. But Poser knows that the missing arguments are not an error.

In any case, I find it very practical, especially since in a CR2 you can achieve the start of a script without the user's intervention and/or knowledge. Great for many things, also to plant viruses and trojans (by the way: to call Poser a "Security Nightmare" is almost a trivialization for this reason).
