Synopsis
[Miscellaneous] ZDateNull=n
n is either 1 (true) or 0 (false). The default value is 0.
Description
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.
Changing This Parameter
On the Compatibility page of the Management Portal (System Administration > Configuration > Additional Settings > Compatibility), in the ZDateNull row, click Edit. Select ZDateNull to enable this setting.
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.
To change this parameter for a single process only (as opposed to instance-wide), use the ZDateNull()Opens in a new tab method of the %SYSTEM.ProcessOpens in a new tab class. See the class reference for details.
