Seeing as how blender is 3d graphics, have you tried the 'newbie
fidget with it', and typed in w(quaternion),x, or y to see what
occurs. Also, have you looked into the hierarchy to see if z, which
looks as though it's contained in a string, is an input variable
declared elsewhere as an integer, or represents something else in it's
usage. Z can mean global, or object orientation in blender from what I
see.
