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

    Validates all parameter values to ensure that they fall within
    the defined minimum and maximum values.

    Because range checks are enabled by default, use PARAMETERS
    ENABLE CHECKS after entering a PARAMETERS DISABLE CHECKS command.

    Format

      PARAMETERS ENABLE CHECKS
