INDEX UPDATE

        [MRTCAL\]INDEX UPDATE [DirName] [/PATTERN String] [DATE DateString]

    Build or update the index of the IMB-FITS files. The index is stored  in
    a  binary file named 'index.mrt'. The command implicitly performs an IN-
    DEX OPEN right after the UPDATE to allow direct use of the index.

    The index lists all the files named 'iram30m-*-*s*-imb.fits' in the  di-
    rectory, including unreadable and incomplete (in terms of number of sub-
    scans) ones. Selection is made from this list with the  various  options
    and features of the commands using this list.

    The  command  can  be called several times. The index file is updated if
    needed, in particular if the file readability has  improved  (e.g.  scan
    has been completed).

    By  default,  the command searches for the IMB-FITS files in the current
    working directory. This can be overriden thanks to the option  /DIRECTO-
    RY.  Note that the index file is always created in the same directory of
    the files it lists (write access is thus needed).  Directory  search  is
    not recursive.
