Mark,

Sorry it took so long to get back to you.  If you send your questions
to "address@hidden" instead, they'll be more likely to be
answered in case I'm away from my email.

The program ncgen generates takes no arguments.  When it is run, it
generates the netCDF file corresponding to the CDL file you gave
ncgen.  So you just need to compile and link the now.c program and run
it to create a "now.nc" netCDF file.  Assuming netCDF is installed in
/local/netcdf/ and your C compiler is named "cc" and you're on a Unix
system, you would use something like:

  $ cc -o now -I/local/netcdf/include now.c -L/local/netcdf/lib -lnetcdf
  $ ./now
  
and you can verify this worked with ncdump, which shows the CDL
version of the netCDF file:

  $ ncdump now.nc
