In RACF, during a terminal session or batch job, the group with which a user is associated for access checking purposes. On MVS, if a user does not specify the current connect group on the LOGON command or batch JOB statement, the current connect group is the user's default group. On CICS, users cannot specify a group other than their default group. If list-of-groups processing is in effect, users are associated with all the groups to which they are connected.
