System and Other FunctionsDescriptionThe $ZUTIL(68,32) function performs two process-specific operations:• It specifies how the $ZDATE function behaves when it receives invalid input.• It specifies the default range of valid dates for $ZDATE. (This provides backwardcompatibilitywith ISM.)$ZUTIL(68,32) only affects the behavior of $ZDATE; the other date and time functions areunaffected.This system-wide default behavior can be configured using the $ZUTIL(69,32) function.For further details on altering the system default for this switch, see $ZUTIL(69,32). Theinitial system default setting of $ZUTIL(68,32) is 0 for all Caché products. The initial defaultsetting of $ZUTIL(68,32) is 1 for all ISM products.Invoking $ZUTIL(68,32) without specifying n returns the current switch setting.ParametersnThe boolean value that specifies $ZDATE behavior. 0 specifies Caché-style behavior; 1specifies ISM-style behavior. The system default setting is 0.NotesCalling $ZUTIL(68,32)When you create a new process, its $ZDATE behavior is initialized from the current settingof $ZUTIL(69,32). Calling $ZUTIL(68,32) overrides this behavior for the current process.Changing the setting of $ZUTIL(69,32) affects only processes subsequently created, notexisting processes.Setting the Behavior for Invalid DatesAn invalid date is either not a positive integer, or is not a value within the range of valid dates,as specified above.$ZUTIL(68,32,0) causes $ZDATE to issue the error message or if you submit an invalid date. The behavior can be overriddenby supplying an erropt parameter to the $ZDATE call.$ZUTIL(68,32,1) 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.620 Caché ObjectScript Reference
$ZUTIL(68,34)Setting the Range of Valid Dates$ZUTIL(68,32,0) sets the default range of valid dates for Caché . This range is from 0 through2980013, inclusive, which corresponds to dates from 12/31/1840 through 12/31/9999. Thisrange can be restricted by setting the $ZDATE mindate and maxdate parameters.$ZUTIL(68,32,1) sets the default range of valid dates for ISM compatibility. This range isfrom 1 through 94232, inclusive, which corresponds to dates from 01/01/1841 through12/30/2098. This date range is set for any $ZDATE function call which has three or fewerparameters. If a $ZDATE function call has more than three parameters, the valid date rangeis taken either from the $ZDATE mindate and maxdate parameters (if specified) or from thedate range established for the current locale.See Also• $ZDATE function• $ZUTIL(69,32) Set Date Range and Invalid Date Behavior function• More information on locales in Customized National Language Translations$ZUTIL(68,34)Sets whether asynchronous errors can interrupt the current process.$ZUTIL(68,34,n)$ZU(68,34,n)ParametersnThe boolean value that specifies whether or not the current process should receiveasynchronous errors.DescriptionThe $ZUTIL(68,34) function specifies whether asynchronous errors can interrupt the currentprocess.This system-wide default behavior can be configured using the $ZUTIL(69,34) function.For further details, see $ZUTIL(69,34).Invoking $ZUTIL(68,34) without specifying n returns the current switch setting.Caché ObjectScript Reference 621
