The Variants Change Clause modifies or removes a variants
    definition within a record definition.

    The NOVARIANTS clause removes a group of variant definitions
    from a record definition. The NOVARIANT clause removes a specific
    variant definition from a record definition.

    To remove a variants definition, use the NOVARIANTS keyword of
    the Variants Change Clause to specify the definitions you are
    removing.

                                   NOTE

       When the CHANGE RECORD command is used to change a variants
       or variant definition or an entity inside a variants
       or variant definition, you must use the Variants Change
       Clause to refer to each variants or variant definition that
       precedes the entity you are changing.
