def setmask(command, data, cdata):
    """
    Sets the mask on a dset and dumps a file containing the mask which can be applied
    to other dsets using 'appmask'. This is an interactive routine which will request
    input from the user and is better not used in batch processing. Repeated calls of
    this routine can be used to build complex masks. The masks are always applied in
    the original order so that you can mask then partially unmask for example. Note that
    whatever slot you choose to define the mask will always end up masked; if you don't
    want this you may want to make a copy.

    Interactive usage:

    setmask slot mfile append [device reset x1 x2 y1 y2] mask type

    Arguments:

    slot      -- an example slot to plot.
    mfile     -- mask file
    append    -- append to an old mask file if possible
    device    -- plot device, e.g. '/xs'
    reset     -- rest plot limits or not
    x1        -- left X plot limit
    x2        -- right X plot limit
    y1        -- bottom Y plot limit
    y2        -- top Y plot limit
    mask      -- mask 'M', or unmask 'U' or quit 'Q'.
    type      -- type of mask: 'X' masks using ranges in X

    Mask types:

    X  -- mask a range in X
    Y  -- mask a range in Y
    I  -- mask a range of pixel indices
    P  -- mask in 'phase', i.e. a range that repeats periodically.
