LOAD /PLANES

        [DISPLAY\]LOAD File /PLANES Min Max

    Read only the last axis "planes" between the  First and Last implied  by
    Min and Max. For an LMV-ordered cube, this would be equivalent to
          LOAD File /RANGE Min Max CHANNEL
    However, for transposed data cubes, VML or LVM-ordered for example, this
    is not true at all when a Frequency/Velocity  axis  is  present:  /RANGE
    would  specify  a  subset  of that axis, while /PLANES always indicate a
    subset of the 3rd axis of the cube.

    Min and Max indicate offsets from Plane  1  and  the  number  of  planes
    Nplane.   Thus Max can be negative: it then indicates Last = Nplane-Max.
    Also Min=0 and Max=0 implies loading all the channels.
