I wish I could. I will need to use z-matrix as I want to do (later) 
relaxed scan of the geometry. I don't think MOLPRO can do this with 
Cartesian (or redundant) coord, cmiiw. So I must stick with Z-matrix.

Here, I just tested simple geometry optimization with CASPT2 (no scan 
yet): As with Cartesian coord it works well, but not with z-matrix.
