The regular structure is used for an RSCV consisting of X'46' control vectors. It is used in BIND processing.
The route selection control vector (RSCV) is carried in BIND, RSP(BIND), and other RUs. It describes the path through an APPN network that a session is to take or has taken. The RSCV is sent and received by APPN nodes, but not by LEN nodes.
