To read an ASCII file, the addfile() function is not the one to use.
If you
view the documentation for addfile:
http://www.ncl.ucar.edu/Document/Functions/Built-in/addfile.shtml
you'll note that there's a link for "supported file formats" for this
function:
http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/
NclFormatSupport.shtml
addfile() doesn't support ASCII-formatted data. However, you can use
asciiread():
http://www.ncl.ucar.edu/Document/Functions/Built-in/asciiread.shtml
Please have a look at the examples on that page, they'll help you
determine how to
format the arguments that asciiread() expects so it can read your data.
-Rick.
