Notes:
  1. VRTGCPCP is meaningful only if the NODETYPE and HOSTSA start options are also used.

Indicates whether CP-CP sessions are supported over the virtual-route-based transmission group.

This option is valid only for interchange nodes and migration data hosts when start options NODETYPE and HOSTSA are specified.

Note: This value can be overridden by coding the VRTGCPCP operand in the CDRM definition statement.
You can change the value of VRTGCPCP with the MODIFY VTAMOPTS command while VTAM® is running.
VRTGCPCP=YES
Indicates that CP-CP sessions are supported over the VR-based transmission group.
VRTGCPCP=NO
Indicates that CP-CP sessions are not supported over the VR-based transmission group.
