        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.
