      The PARAMETERS ENABLE CHECKS command in this example shows
      that when range checking is disabled, the system accepts a
      working set value (WSMAX) of 20. However, once range checking
      is enabled with the PARAMETERS ENABLE CHECKS command, the
      system does not accept a WSMAX below the minimum, which is
      60.
