MODIFY HEADER

            CLIC\MODIFY HEADER procedure

        This is a general command to edit the header of the scans in the current
        index..   CLIC  enters  a loop in which all the headers are read succes-
        sively.  For each header the procedure  'procedure'  (default  extension
        ".clic")  is  executed.   This  procedure may only contain the following
        commands : DUMP, HEADER, 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 scan
        header will be updated; with only GO, the scan header is not updated and
        CLIC  loads the next scan header in the current index.  If no GO command
        in encountered in the procedure, the loop is aborted.  If a  PAUSE  com-
        mand  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.
