Some fill values defined in fortran include file netcdf.inc differ from
those in C include file netcdf.h
netcdf.inc:
parameter(FILBYTE = 128)
parameter(FILSHORT = 32768)
parameter(FILLONG = -2147483648)
netcdf.h:
#define FILL_BYTE ((char)-127) /* Largest Negative value */
#define FILL_SHORT ((short)-32767)
#define FILL_LONG ((long)-2147483647)
The values in netcdf.h appear to be correct. All three values in netcdf.inc
are silly. The max. value for a byte is 127, while the max for a short is
32767. Thus the values for FILBYTE & FILSHORT are impossible! The min. for
a long is -2147483648, but some software has trouble with this number
because its magnitude exceeds that of the max. 2147483647. So it is safer to
use -2147483647 as FILLONG.
