System and Other Functionsa $ZDATE function call has more than three parameters, the valid date range is taken eitherfrom the $ZDATE mindate and maxdate parameters (if specified) or from the date rangeestablished for the current locale.The default setting of $ZUTIL(69,32) is 0 for all Caché products, and 1 for all ISM products.Setting the Behavior for Invalid DatesAn invalid date is either not a positive integer, or is not a value within the range of valid dates,as specified above.$ZUTIL(69,32,0) causes $ZDATE to issue the error message or if you submit an invalid date. The behavior can be overriddenby supplying an erropt to the $ZDATE call.$ZUTIL(69,32,1) causes $ZDATE to return the null string if you submit an invalid date.This behavior is set for any $ZDATE function call, regardless of the number of parameters.This configuration default cannot be changed using the System Management Portal.Setting $ZUTIL(69,32) overrides the System Configuration default; it does not change thedefault setting.Calling $ZUTIL(69,32)When you create a new process, its $ZDATE behavior is initialized from the current SystemConfiguration default and $ZUTIL(69,32). Calling $ZUTIL(68,32) overrides this behaviorfor the current process. Changing the setting of $ZUTIL(69,32) affects only processes subsequentlycreated, not existing processes.See Also• $ZDATE function• $ZUTIL(68,32) Set Date Range and Invalid Date Behavior function• More information on locales in Customized National Language Translations666 Caché ObjectScript Reference
