property variant UndefValue
This property specifies the value returned when the Analytica value is Undefined. By default, ADE returns the special value variant Empty — for example, when GetAttribute is applied to an attribute that was not set. Some scripting languages cannot manipulate the value Empty. In this case, you can set UndefValue to something more convenient, such as Null or the empty string.
