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.
