This property is relevant when the server application is configured in Visual OSA to use ASOLib. Its value is defaulted when the ASOSession object is created, but it can be changed before issuing a Connect or AttachRSO method.

The property value is used to specify a numeric user identifier. It is used for identification purposes only (for example, when using Visual OSA session monitoring). The default value is the client process number.
