GET

        CLIC\GET [n|FIRST|NEXT] [/RECORD r] [/HEADER] [/ATM]

    GET loads the observation number n. If n is absent, the  previous  (last
    read)  observation  is  recovered.  If  instead  of a number the keyword
    "FIRST" is given, the first observation of the current index is  loaded.
    With "NEXT", the next observation in the current index is loaded.

    If  option  /RECORD  is present, only record r is loaded. Otherwise, the
    average record is loaded; it contain by default the uncorrected data un-
    less option /ATM is present, in which case the phase-corrected record is
    loaded if it exists.

    If option /HEADER is present, only the scan header  is  read.   No  data
    record  is  accessed. This command does not access the data file if only
    the header file is available.
