Re: Changing Directories in the middle of an NCL script

Was your question answered?
==============================
Another variation

      dirA = "/.../.../"
      dirB = "/.../.../"
      dirC = "/.../.../"

      diri = (/dirA, dirB, dirC/)

      filA = "fooA"
      filB = "fooB"
      filC = "fooC"

      fili = (/filA, filB, filC)

      NN = dimsizes(fili)
      do n=0,NN-1
           fnam = systemfunc("cd "+diri(n) +" ; ls *"+fili(n)+"*")
           nfnam = dimsizes(fname)
            ..........
           delete(fnam) ; maybe different # of files next iteration
      end do
