Spazm,
Go here
http://www.ncl.ucar.edu/Applications/list_io.shtml
and here
http://www.ncl.ucar.edu/Applications/read_ascii.shtml
an you should be able to find the function that will work for you. It will
probably be readAsciiTable
You will have to tailor it to work with your file. There are many examples to
follow on that page.
