Howdy Julia!

The good news is that there is nothing to fix, apparently. The simple_xy_read
program is reporting that it has successfully read the simple_xy.nc file, and
got expected values. Unless it finds problems, it only prints out the one
line:

*** SUCCESS reading example file simple_xy.nc!

If you take a look at the code, which is also available on-line:
http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-tutorial.html#simple_005fxy-in-F90

you will see where you can add your own code to print out the values that are
being read.

Thanks, and keep on netCDFing!
