Specifies the subarea part of the real address for the CDRM in the network of the gateway SSCP. The real address is an address in the associated gateway NCP.
For a gateway SSCP, code SUBAREA if you do not code GWN. You can use SUBAREA instead of GWN when the gateway NCP has different node names but always has the same subarea number. See the description of the GWN operand.
The gateway SSCP uses this value if you do not code GWN, or if it does not have a session with the associated gateway NCP when VTAM® starts the other network’s CDRM.
