/************************************************************

  This example shows how to set the fill value for a

  dataset.  The program first sets the fill value to

  FILLVAL, creates a dataset with dimensions of DIM_XxDIM_Y,

  reads from the uninitialized dataset, and outputs the

  contents to the screen.  Next, it writes integers to the

  dataset, reads the data back, and outputs it to the

  screen.  Finally it extends the dataset, reads from it,

  and outputs the result to the screen.
