This might be a bug.  I'll have to check it at home where the superpatch source
code is and see what's going on. In the meantime, it might work if you do 
#declare foo=POS(I/Steps) and then use abs(foo.z).

http://pandora.inf.uni-jena.de/pframe.phtml/e/noo/povsp/povsp.inc is Wolfgang
Ortmann's page for the spline patch.  It includes the same documentation that
has been included with the superpatch (though I rewrote it slightly) and there
is a small tutorial as well.  The code, however, is for POV version 3.01.
