The CLASSDEF statement
- CLASS(TCNEW) - specifies TCNEW as the name of the transport class.
- GROUP(NEWAPP) - assigns group NEWAPP to transport class TCNEW.
The defaults are taken for CLASSLEN and MAXMSG parameters.
MVS™ defines the DEFAULT transport class automatically. In this case, because the group NEWAPP is assigned to a transport class, UNDESIG refers to all groups except NEWAPP.
