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. ]
