Setting n changes this behavior for local variables, process-private globals, andglobal variables systemwide; it has no effect on special variables.$ZUTIL(69,0) only affects variables invoked by subsequent processes; it does not affect thecurrent process. To set handling of undefined variables for the current process, use the$ZUTIL(18) Undefined Variable Behavior function.The value you assign to the variable n becomes the system-wide default behavior for allsubsequently initiated processes. The native default setting is 0, which specifies that allundefined variables result in the error message.Invoking $ZUTIL(69,0) without specifying n returns the current switch setting.The system-wide default behavior is configurable. Go to the System Management Portal,select System Configuration, select Advanced Settings, on the pull-down Category list selectObjectScript. View and edit the current setting of UndefVarBehavior. The default is 0.Setting $ZUTIL(69,0) overrides the System Configuration default; it does not change thedefault setting.ParametersnA numeric code that specifies how Caché treats an undefined variable:634 Caché ObjectScript Reference
