For example:

%> cd /Users/appo/Data/IGRA2


drwxr-xr-x    4 2200     136 Apr 29 13:43 RAOB/
-rw-r--r--@   1 2200    3008 Apr 29 12:06 igra2-country-list.txt
-rw-r--r--@   1 2200  245729 Apr 29 12:07 igra2-station-list.txt
-rw-r--r--    1 2200    8489 Apr 29 14:21 rdIGRA2.ncl

The RAOB directory could have many files but for test just one.

-rw-rw-r--@ 1 2200  12956441 Apr 27 16:42 GBM00064500-data.txt

%> ncl rdIGRA2.ncl

[The actual print out looks nicer.   ]
