This parameter has been retained for compatibility, but should not be used when building new applications.

ZDateNull determines how a $ZDATE call responds when triggered by an invalid value. When this parameter is enabled, $ZDATE returns a null value. When this parameter is not enabled, it returns an error.

Instead of using the Management Portal, you can change ZDateNull in the Config.MiscellanousOpens in a new tab class (as described in the class reference) or by editing the CPF with a text editor.
