NEW_DATA

        CLIC\NEW_DATA [time] [tries]

    Waits  until  new  data has been written to the input file, then makes a
    new index from all new data. The type of observation can be  changed  by
    this  command, but the index will contain only observations of one type.
    Selection criteria defined by command SET are ignored.

    This command can be used to make a quick look or analysis of  data  pro-
    duced by a real time acquisition system (Plateau de Bure).  Caution: on-
    ly two programs should access the input  file  simultaneously,  one  for
    writing the other for reading.

    The  first argument is the time interval between two consecutive inspec-
    tions of the file index; the second is the allowed number of  unsuccess-
    ful  attempts  to find new data in the file. The defaults are 10 seconds
    and 12 tries (two-minute timeout).
