Read/write session states

A read/write session can be in one of three states, as illustrated in the following figure. When the session is opened, it is in either the "R/W Public Session" state (if the application has no previously open sessions that are logged in), the "R/W User Functions" state (if the application already has an open session that the normal user is logged into), or the "R/W SO Functions" state (if the application already has an open session that the SO is logged into).
