  This In-Form case creates a non-moving In-Form object, either
  a box or a sphere, in either a cartesian or a cylindrical-polar
  grid

  The three In-Form-specific commands are:

  1. PATCH(PATCH1,CELL,1,NX,1,NY,1,NZ,1,LSTEP)
     which defines the space within which the object will be placed;

  2. (INFOB at PATCH1 is SPHERE(:xce:,:yce:,:zce:,:radius:)      wi$
th INFOB_1)
     which defines the sphere by way of its centre coordinates and
     radius; and

  3. (STORED of MARK at PATCH1 is 1. with INFOB_1)
     which sets the value of a variable named MARK to the value 1,0
     within the object IBFOB_1 within PATCH1 .

  Of course, PIL statement are also provided which:
  * define the grid,
  * declare xce, yce, zce, and radius as character variables,
  * ascribe values to them,
  * STORE, and assign a zero initial value to, MARK .
