[molpro-user] variable holding cartesian coordinates

Ok, if I understand correctly, only those geometric variables explicitly specified by the user are 
"available" for use in a MOLPRO input script.  Yet surely the cartesian coordinates of the atoms 
must be stored in some form in the program.  I would find it very useful to be able to access 
these coordinates for calculation of geometric parameters when using variable-based Z-matrix 
input, rather than having to back-calculate them from the Z-matrix coordinates as I do now.

So, would it be possible to add a keyword that allows the user to explicitly specify that the 
cartesians be stored as accessible variables (perhaps read-only), along with the usual Z-matrix 

I guess I am not the only one for whom this would be a desirable feature.
