Re: Changing Directories in the middle of an NCL script

Each "system" call executes one set of commands in the shell, and
once you leave it, it returns to its original state.

So, if you use "system" to cd to a directory, you won't still be
in that directory if you call "system" again.

You can use the UNIX ";" character to execute a series of UNIX commands:

  cmd = "cd DIR1 ; do_what_im_doing_in_DIR1 ; cd DIR2 ; do_what_im_doing_in_DIR2"
  system(cmd)
