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

Indicates whether VR-based transmission group connections are to be requested when the SSCP-SSCP session is established for this node.

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 VRTG operand in the CDRM definition statement.
You can change the value of VRTG with the MODIFY VTAMOPTS command while VTAM® is running.
VRTG=YES
Indicates that VR-based transmission group connection is requested when SSCP-SSCP sessions are established.
VRTG=NO
Indicates that virtual-route-based transmission group connection is not requested when SSCP-SSCP sessions are established.
