C       This part has been placed in an #ifdef because, as its currently
C       written, it will only work with variables defined on a dynamics
C       grid.  As we start using diagnostics for physics grids, ice
C       levels, land levels, etc. the different vertical coordinate
C       dimensions will have to be taken into account.

C       20051021 JMC & EH3 : We need to extend this so that a few
C       variables each defined on different grids do not have the same
C       vertical dimension names so we should be using a pattern such
C       as: Z[uml]td000000 where the 't' is the type as specified by
C       gdiag(10)
