Library /sys$common/syshlp/sysmanhelp.hlb PARAMETERS, ENABLE, CHECKS, Example  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  SYSMAN> PARAMETERS DISABLE CHECKS
  SYSMAN> PARAMETERS SET WSMAX 20
  SYSMAN> PARAMETERS ENABLE CHECKS
  SYSMAN> PARAMETERS SET WSMAX 30
  %SMI-E-OUTRANGE, parameter is out of range
  SYSMAN> PARAMETERS SHOW WSMAX
  Parameter Name    Current  Default  Minimum  Maximum Unit  Dynamic
  WSMAX                2000     1024       60   6400 pages

      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.
