Hi-

I use a modified version of the BatchProcessFolders Macro to analyze all
the images in a folder.  In order to be as objective as possible, I
would like to randomize the order that the images are processed (I have
already blanked out the filename, so I cant cheat that way).  Here is a
snippet of the macro that call sends each file to processFile-

  function processFiles(dir) {
       list = getFileList(dir);
       for (i=0; i<list.length; i++) {
           if (endsWith(list[i], "/"))
               processFiles(""+dir+list[i]);
           else {
              showProgress(n++, count);
              path = dir+list[i];
              processFile(path);
           }
       }
   }

The array list then would contain the ordered list of files.  Is there a
way to randomize the order of these file in the array using the macro
language?

Thanks for the help, Mike
