MODIFY RECORD

        CLIC\MODIFY  RECORD procedure [/RECORD idump] [/BEFORE date] [/AFTER
    date]

    This is a general command to edit the data headers of the scans  in  the
    current  index.   CLIC enters a loop in which all the data header of all
    records of all scans in the current index are read successively.  In the
    case the option "/RECORD idump" is used, only the record number idump is
    read.  For each record  the  procedure  'procedure'  (default  extension
    ".clic")  is  executed.   This  procedure may only contain the following
    commands : DUMP, HEADER, FLAG, MINMAX, GO, or any SIC command that  acts
    on  variables. Especially, variables 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.
