                                  shows indexes for the previous date each time
                                  you press the "Prev"
                                  button. 
 This button will become ineffective if you
                                  have reached the first date (start date). The
                                  start date might be your pre-processed
                                  database's first date or the current report's
                                  start date, set by you through "change
                                  date" option.
