Record 1:       FORMAT(I10,20A1)
                Field 1      -- View number
                Field 2      -- 20 character view description
Record 2:       FORMAT(6I10)
                Field 1      -- Z-Clip flag
                                Z-clipping (front and back clipping
                                distances) enabled (1) or disabled (0).
                Field 2      -- Perspective flag
                                = 0 - disabled.
                                = 1 - enabled.
                Field 3      -- Perspective value type
                                = 0 - by field of view angle
                                = 1 - by distance
                Field 4      -- Pre-transformed world clip flag
                                = 0 - disabled.
                                = 1 - enabled.
Record 3:       FORMAT(6E13.5)
                Field 1-3    -- View target
                                The 3D world location to place in
                                the center of the screen. All screen
                                and dial rotations are done about the
                                objects target.
                Field 4-12   -- Rotation matrix
                                3X3 roation matrix gives rotation of
                                object about the view target.
                Field 13     -- Window radius
                                Defines the size of the short axis of
                                the view window in world units.
                Field 14     -- Front clipping distance
                                Defines the world distance from target
                                to front clipping plane.
                Field 15     -- Back clipping distance
                                Defines the world distance from target
                                to back clipping plane.
                Field 16     -- Perspective value
                                If perspective flag = 0,
                                   view angle in degrees (5.0 < X < 85)
                                Else if perspective flag = 1,
                                   world distance of eye from target
                                   along the screen Z axis
                Field 17-22  -- Pre-transformed world clip boundaries
                                The world clip box is specified by the
                                rear, lower, left-hand corner (MIN) and
                                front, upper, right-hand corner (MAX).
