1 DIRECTORY
        FITS\DIRECTORY Dir0me

    Lists specified directory. Only meaningful for disks and CDroms...

1 DISMOUNT
        FITS\DISMOUNT

    Dismounts  and  unloads  currently  mounted  removable   medium   (Tape,
    CDrom...).

1 INITIALIZE
        FITS\INITIALIZE

    Initialize the tape. It must be logically mounted to do so...

1 Language
                    CLASS to FITS traductor language
    DIRECTORY    : Lists all files in a directory
    DISMOUNT     : Dismount and unloads the tape
    INITIALIZE   : Initialize the tape
    HEADER       : List the header of current FITS file.
    LIST [key]   : List the headers of all files from current position.
    MOUNT [Dev:] : Logically mount the tape on the specified device.
    READ         : Read scan from current FITS file.
    REWIND       : Rewind tape (but doesnot dismount it).
    SELECT       : Define writing parameters
    SKIP N       : Skip N (positive or negative, * for all) files on tape.
    WRITE        : Write the current scan or index in FITS format.

1 LIST
        FITS\LIST [keyword]

    List the headers of all files from current tape position, or  list  only
    the specified FITS keyword.
1 MOUNT
        FITS\MOUNT Device

    Logically mount the removable medium on the specified  device.  (Logical
    name  TAPE_DEVICE  is used by default). This command must be used before
    anything else is done on device (even INIT for tapes). If it was already
    mounted by the user, the tape is rewound.
1 READ
        FITS\READ [File0me] [/CHECK]

    This command is used to Read data from FITS format.  Not all FITS  tapes
    may  be  read  by CLASS, and some header information might be incomplete
    when doing so.

    On tape, the new scan is read from current tape position, and  the  tape
    is  left  at  the  beginning of next file. On disks and CDroms, the file
    name argument is compulsory.

    Option /CHECK can be used to list the header while reading the file.
1 REWIND
        FITS\REWIND

    Rewinds the tape (but does not dismount  it).  Although  CFITS  normally
    keeps  track  of file numbers on tape, it used to occasionally get lost.
    In the unlikely event that this happens again, rewinding is the only way
    to recover correct numbers.
1 SELECT
        SELECT Parametre Value

    Defines optional parametres to be used when writing a tape.
      - SELECT FORMAT Form
        Determines the format to be  used  on  the  output  tape.  Currently
        supported  formats are I*2 and I*4. They correspond to BITPIX=16 and
        BITPIX=32 in FITS header.

1 SKIP
        FITS\SKIP N

    Skip N (positive or negative) files on tape. If N = *, move  to  end  of
    tape.

1 WRITE
        FITS\WRITE [argument] [/CHECK]

    This command is  used  to  write  data  in  FITS  format.  The  argument
    interpretation  depends  on the current device. In disk mode (before any
    MOUNT was issued), it is interpreted as the name of the  FITS  file.  On
    tape, there are three possibilities:
      - FITS\WRITE *
        writes all the scans currently selected in the CLASS index at end of
        tape. This command is the most efficient way to write a FITS tape.
      - FITS\WRITE
        writes the current scan at the end of the tape
      - FITS\WRITE HERE
        writes the current scan at the current tape position.
    Option /CHECK may be used to list the FITS header while writing the tape
    files.
