  This In-Form case describes immovable In-Form object.

  This object is specified by INFOB commands, wherein the
  formula takes the form:

    SPHERE(x-centre, y-centre, z-centre, radius) ,

  each of the arguments is itself a formula.

  The following In-Form formulas set pump chamber:

  char(xce,yce,zce,radius)
  xce=10.; yce=10.; zce=10.; radius=8.
  (INFOB at PATCH1 is SPHERE(:xce:,:yce:,:zce:,:radius: ...
  ) with INFOB_1)

  PATCH(PATCH2,CELL,1,NX/2,1,NY,1,NZ,1,LSTEP)
  xce=XG; yce=16.; zce=10.; radius=2.
  (INFOB at PATCH2 is SPHERE(:xce:,:yce:,:zce:,:radius: ...
  ) with INFOB_1)

  PATCH(PATCH3,CELL,NX/2+1,NX,1,NY,1,NZ,1,LSTEP)
  xce=XG; yce=4.; zce=10.; radius=2.
  (INFOB at PATCH3 is SPHERE(:xce:,:yce:,:zce:,:radius: ...
  ) with INFOB_1)

  The following formula defines MARK variable.
  MARK is used by PHOTON for marks of borders of a pyramid.

  FIINIT(MARK)=1.0
  *** Setting of MARK values inside spheres
  (INITIAL of MARK at PATCH1 is 0. with INFOB_1)

  The Q1 contains PHOTON USE commands
