! !DESCRIPTION:
!   Write the fields out for purview.  This function overcomes certain
!   difficulties in passing strings with an optional number of arguments.

!   \begin{description}
!   \item [grid]
!         grid to write
!   \item[{[staggerLoc]}]
!         stagger of field
!   \item[filename]
!         File (stub) to write results to
!   \item [{[array1-6]}]
!         Arrays to write as data
!   \item [{[rc]}]
!         Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
