MODIFY DATA

            CLIC\MODIFY DATA procedure [/BEFORE date] [/AFTER date] [/ATM]

        This is a general command to edit the data headers of the scans  in  the
        current  index. CLIC enters a loop in which for all scans in the current
        index, the data header of the average record is read. For each scan  the
        procedure 'procedure' (default extension ".clic") is executed. This pro-
        cedure may only contain the following commands  :  DUMP,  HEADER,  FLAG,
        MINMAX, GO, or any SIC command that acts on variables. Especially, vari-
        ables defined by the VARIABLE command can be modified...

        The command GO [WRITE] must end the procedure.  With GO WRITE, the  data
        record will be updated; with only GO, the data record is not updated and
        CLIC loads the next record from the current index.  If no GO command  in
        excountered  in  the procedure, the loop is aborted.  If a PAUSE command
        is found in the procedure, the PAUSE is executed, but the prompt changes
        to  "MODIFY>".  The same commands as above may then be executed from the
        keyboard; "QUIT ALL" may be used to abort the loop.

        The options /BEFORE and /AFTER allows to select data depending on  their
        observing dates.

        If  present,  the  /ATM  option  allows to modify the data header of the
        phase corrected average record (will work only if such record is present
        in  the  data,  so  only on cross-correlations: CROSS, FLUX, POINT, GAIN
        ...)
