Accessing the mass store from NCL

NCL can issue read/write commands to the MSS via the system procedure:
    system("msread local_file_name /SHEA/ccm3/hist/")
One could put this in a loop to bring over files one at a time and process them:
    do n = 0, nfiles-1
      system("msread" + year(n)+".nc /SHEA/ccm3/hist/"+year(n)+".nc")
      in = addfile(year(n)+".nc","r")
      process file
    end do
