No dice, at least not yet. Altered the code to:

import poser
import random
scene=poser.Scene()
scene.SetFrame(23)
scene.SelectFigure(scene.Figure('Terri'))
actor = scene.Actor('Left Shin')
parm = actor.ParameterByCode(poser.kParmCodeBEND)
parm.SetValue(88)

but got the error -

 in
    parm = actor.ParameterByCode(poser.kParmCodeBEND)
AttributeError: 'module' object has no attribute 'kParmCodeBEND'

Aren't there some simple examples online? I've found a few sites claiming to be intros to Poser Python, but they are "Hello World" programs. I want to manipulate Poser, not figure out how to say "Hello World"  ;)
