The differences between the old rmn_007 interface and the new rmn_008 interface are described here.

N.B.:
It should be noted that this interface is not supported on azur. This interface is DEPRECATED on all computers.

DIFFERENCES FROM THE CURRENT INTERFACE:

1. To have access to the type(T_VerticalGridIfc) definition, you must have:
#include < ViTypes_f90.h >

2. The function names, N_ViqkdefIfc_X and N_VidefsetIfc_X, are replaced by the function names, N_ViqkdefIfc and N_VidefsetIfc. These two names must be declared explicitly:
integer N_ViqkdefIfc, N_VidefsetIfc

3. The *_X versions accept indices as arguments where the * versions accept T_VerticalGridIfc objects instead, declared thus:
type(T_VerticalGridIfc), target :: gridInitial, gridTarget

4. N_VidefsetIfc does not contain the four *ExtArrays* parameters of N_VidefsetIfc_X.
