access to I/O facilities to aid the user in examining the results of 
computations.  As discussed in section 2.3, there 
is currently one pre-defined 
attribute:  out_gf.  If the special 
parameter  fout is set, then every  rmod time steps, output 
is generated for every grid function for which output has been
enabled via  out_gf.  Output is to  .hdf files: one
file for each selected grid function is created, and each file 
consists of a sequence of dumps labelled with the actual output 
time.  These files can then be post-processed with a variety 
of software, including the Explorer module,

The interface to the lower level .hdf routines is also directly accessible from C or Fortran codes which have not been generated using RNPL and is described in The RNPL User's Guide.
