Specifies the TG number that represents the connection between the host to which this PU definition statement applies and either a communication controller or another host.
Coding TGN=ANY allows the adjacent subarea node to accept whatever valid TG number it receives on the XID.
You can specify TGN=ANY only for the PU at one end of a transmission group. The PU at the other end must have a valid transmission group number or default to 1. An error occurs if you specify TGN=ANY for both PUs.
