Perhaps you haven't included the "netcdf.inc" file that contains the
PARAMETER statement defining NCNOCLOB and other netCDF Fortran symbols.  In
the netcdf.inc file, NCNOCLOB is defined by:

      parameter(NCNOCLOB = 15)

If you have included netcdf.inc with a statement such as

      include 'netcdf.inc'

then, something  before the call to NCCRE must have caused the value of
NCNOCLOB to be overwritten, even though PARAMETER values are supposed to be
constant.  You could tell if this is the case by printing the value of
NCNOCLOB before the call.
