/LIST=file_spec
  /NOLIST

  Creates   an  output  listing  showing  the  input  file,  coordinate
  positions,  and compilation statistics. If the file specification  is
  not  provided, the output file name is the input file name,  with the
  file type LIS.  The  /NOLIST qualifier disables listing  output.  The
  default  depends  on the current mode of the process.  If the mode is
  interactive,  the  default  is  /NOLIST;   if the mode  is batch, the
  default is /LIST.
