[Dennis Shea]

Please read:

http://www.ncl.ucar.edu/Document/Functions/Contributed/generate_sample_indices.shtml
=============
N = 30
file_names(N)

Your choice

iwo = *generate_sample_indices*( N, 0 )
 iw = *generate_sample_indices*( N, 1 )


Use 1st 10

   M = 10

   file_names(iw(0:M-1))
   file_names(iwo(0:M-1))
