RRF 3.1.1 move.axes[0].userPosition=move.axes[0].userPosition/2

I'm trying to make a hole probe macro with RRF 3.1.1
Is it possible to read current axis work position and divide it by 2?
The below does not work: move.axes[0].userPosition=move.axes[0].userPosition/2
but is it possible to achieve this in some other way?::Rickard::

Wouldn't you just need to do the following?
G0 X{move.axes[0].userPosition/2}

Thanx! woprks very well now. This is what I ended up with.
M558 K0 P5 C"!io2.in" F100; create probe #1 for use with M585, active low
