Proof of concept?
It can be done.
I have not used Forces nor animation in Blender, yet. Sounds like fun. :-)

because sometimes <Norm> is equal to <0.000, 1.000, 0.000>
then, you caculate VerAng with :
#local VerAng = VAngleD(<Norm.x, 0, Norm.z>, Norm);
first parameter become <0.000, 0.000, 0.000>
VAngleD use vnormalize that is not defined for a null vector.
and you get :
Possible Parse Error: Normalizing zero-length vector.
you can, for exemple, correct this by adding smalls values to <Norm>
#if ((Norm.x = 0.0) & (Norm.z = 0.0))
#local Norm = <0.0001, Norm.y, 0.0001>;
#end

no visible difference in fact :)

Simple and effective indeed. Thank you. I had difficulty in visualizing
what was exactly happening.
