  DISPLAY
  In-Form is used to set an initial sinusoidal temperature
  in an insulated slab of aluminium.
  The temperature distribution flattens with time, retaining
  however its sinusoidal shape, as is made evident by the
  line-printer plots elicited by PATCH(PLOT,PROFIL,,,,,
  Setting IDISPA=20 causes a parphi file to be created, with
  20 time intervals, enabling the temperature variation to be
  viewed via PHOTON.
