Hi Ben,

I think that example was in error and was corrected in the User's Guide some
time ago.  The example now reads:

    Here is an example using NCVDEF to create a variable named rh of type
    long with three dimensions, time, lat, and lon in a new netCDF file
    named foo.nc:

          INCLUDE 'netcdf.inc'
             ...
          INTEGER  NCID, RCODE
          INTEGER  LATDIM, LONDIM, TIMDIM ! dimension IDs
          INTEGER  RHID                    ! variable ID
          INTEGER  RHDIMS(3)               ! variable shape
             ...
          NCID = NCCRE ('foo.nc', NC_CLOBBER, RCODE)
             ...
                                           ! define dimensions
          LATDIM = NCDDEF(NCID, 'lat', 5, RCODE)
          LONDIM = NCDDEF(NCID, 'lon', 10, RCODE)
          TIMDIM = NCDDEF(NCID, 'time', NCUNLIM, RCODE)
             ...
                                           ! define variable
          RHDIMS(1) = LONDIM
          RHDIMS(2) = LATDIM
          RHDIMS(3) = TIMDIM
          RHID = NCVDEF (NCID, 'rh', NCDOUBLE, 3, RHDIMS, RCODE)
