12. Infinite Circular Cylinder parallel to a coordinate axis. Code: XCC, YCC, ZCC

      A XCC (YCC, ZCC) is an infinite circular cylinder parallel to the
      x (y, z) axis.
      Each XCC (YCC, ZCC) is defined by 3 numbers:
      A_y, A_z (A_z, A_x for YCC, A_x, A_y for ZCC) (coordinates of the
      cylinder axis), R (cylinder radius)
      An XCC (YCC, ZCC) definition, in fixed format, extends always over one
      single card.

      Example in default fixed format:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7..
XCC 013 -480.0 25.0 300.0
* (an infinite cylinder of radius 300 cm, with axis defined by y=-480,
* z=25)
ZCC 014 0.0 0.0 2.5
* (an infinite cylinder of radius 2.5 cm, with axis equal to the z axis)
The same example in high-accuracy body fixed format:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+.
XCC 013 -480.0 25.0 300.0 ZCC 014 0.0 0.0 2.5 The same, in free format: XCC Column -480.0 25.0 300.0 ZCC Tunnel 0.0 0.0 2.5
