If VTAM® is started at A81 with the start option GWSSCP=YES, A81 is considered to be a gateway VTAM. The GWPATH definition statements in the CDRM major node for A81 define possible cross-network session paths between the gateway host CDRM and a CDRM in another network. A NETWORK definition statement defines NETB as the network in which the cross-network external CDRMs reside.
