On CDRM

Specifies the number of the subarea in which this CDRM resides.

The SUBAREA value for each subarea used in cross-domain or cross-network communications must be unique throughout the network, but not throughout a set of SNA interconnected networks. For a host CDRM, this SUBAREA value must be the same as the host’s subarea specified by the HOSTSA start option.

If no GWPATH definition statements follow the other-network CDRM definition statement, code the SUBAREA operand on that CDRM definition statement. The SUBAREA operand must represent a valid subarea number in this network for a gateway NCP.

GWPATH provides subarea information. It is not required for cross-domain communication, but is required for cross-network communication if the following conditions exist:
  • CDRM is defined for the same network
  • GWSSCP=YES in the START options and this CDRM is defined for cross-network sessions
