Not exactly. The input is: 1 2 And process runs independently for each of those two items. So '/home/user/input/filename1.pgm' and '/home/user/input/filename2.pgm' do not exist together in the same instance of process"0. > what I want is to "separately" process each array.

It does indeed go for one array at a time. The issue here is that you have changed the mechanism so the result of the process is the input file name. And the results are preserved, so they exist simultaneously. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
