  ** CURRENT SYSTEM UNIT NUMBER VALUES **     (0 IF UNUSED)

  BINARY USER ON/OFF CONTROL:
  USER APPLICATION OPTION ........ N_TAPE1 
  USER APPLICATION OPTION ........ N_TAPE2 
  USER APPLICATION OPTION ........ N_TAPE3 
  USER APPLICATION OPTION ........ N_TAPE4 
  USER APPLICATION OPTION ........ N_TAPE5 

  FORMATTED I/O DEFAULTS:
  STANDARD INPUT ................. N_CRD   
  STANDARD OUTPUT ................ N_PRT   
  DEBUG OUTPUT ................... N_BUG   

  FORMATTED RESULTS (AND MATLAB PLOTS):
  RESULT msh_bc_xyz.tmp .......... U_PLT1  
  RESULT msh_nodes.tmp ........... U_PLT2  
  RESULT node_results.tmp ........ U_PLT3  
  RESULT el_qp_xyz_fluxes.tmp .... U_PLT4  
  RESULT scp_node_averages.tmp ... U_PLT5  
  RESULT el_error_est.tmp ........ U_PLT6  
  RESULT pt_ave_error_est.tmp .... U_PLT7
  EXACT exact_node_solution.tmp .. U_PLT8
  EXACT exact_node_flux.tmp ...... U_PLT9
  Note: CALL TURN_OFF_PLOTS available.

  BINARY INTERNAL DEFAULTS:
  SYSTEM REACTION STORAGE ........ N_REACT 
  ELEMENTS REACTION STORAGE ...... L_REACT 
  SUPER_CONVERGENT_PATCH ......... U_SCPR  
  Note: CALL TURN_ON_SCP, CALL TURN_OFF_SCP available.
  ELEMENT FLUX DATA .............. U_FLUX  
  ELEMENT INTEGRATIONS ........... U_INTGR 

NOTE: This list is displayed with current numerical values by a
      CALL LIST_SYSTEM_UNIT_NUMBERS.  Then you can check a unit 
      by a CALL INQUIRE_ABOUT_UNIT (unit) for current status.

      CALL LIST_OPEN_IO_UNITS is available.

      Now temporary file units are not assigned unit numbers in advance.
      Instead the next available unit is assign by a function. Namely
      NEXT = GET_NEXT_IO_UNIT ()
