Fernando,

Why do you want to read in a NetCDF file and write the values out to an ASCII file?

If you are doing this for several variables across time and levels, you are going to end up with a really big ASCII file. Also, it's not easy to represent multiple dimension arrays in an ASCII file.

If I know more about why you need an ASCII file, then there may be a better solution.
