The locale affects the representation of data formatted, validated, or normalized by picture clauses. When this property is absent or empty, the default behavior is to inherit the parent object’s locale. If the outermost subform does not specify a locale, the default behavior derives from the ambient locale of the operating system. If the operating system does not supply a locale, en_US is used.
