When a system is automatically connected, two logons take place for thesource system in question: First, there is a dialog box logon with thespecified host. A logon screen appeared for this logon. During the call,the system determined the name &V3& for the system to be connected.Then, a second logon occurred with the specified destination or with thedestibation entered in BW in the RSLOGSYSDEST table in LOGSYS = &V3& .During this logon, the system determined the name &V1& .
