8.2.4.10} Infinite half-space delimited by a coordinate plane. Code: XYP,XZP,YZP

      There are 4 kinds of infinite half-spaces. Three of them are delimited by
      planes perpendicular to the coordinate axes:
      Delimited by a plane perpendicular to the x-axis. Code: YZP
             or by a plane perpendicular to the y-axis. Code: XZP
             or by a plane perpendicular to the z-axis. Code: XYP
             Each of these half-spaces is defined by a single number:
             V_x (resp. V_y, or V_z), the coordinate of the plane on the
             corresponding perpendicular axis.
             The half-space "inside the body" is the locus of points for
             which x < V_x (resp. y < V_y, or z < V_z).
      An YZP, XZP, XYP definition, in fixed format, extends always over
      a single line.

      Example in default fixed format:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7..
YZP 71 -44.2 XZP 72 108.0 XYP 73 0.0
* (respectively, all points having x < -44.2, those having y < 108,
* and those having z < 0).
The same example in high-accuracy body fixed format:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+.
YZP 71 -44.2 XZP 72 108.0 XYP 73 0.0 The same example in free format: YZP horizPla -44.2 XZP vertPla1 108.0 XYP vertPla2 0.0
