Re: How to read GRIB files without explicit file format extension

Hi Zhuming,

The file itself doesn't physically need to have the ".grb" extension,
but "addfile" *must* have the extension so that it knows how to open
the file.

For example, if you have a file called "ruc", and you run
NCL with:

   f = addfile("ruc.grb","r")

then NCL will first look for a "ruc.grb" file, and if it doesn't find
this, it will look for a "ruc" file, and try to open it as a GRIB
file.
