Implicit sign-on and implicit sign-off

Implicit sign-on means that all other userids added to the system by CICS are considered to be implicitly signed on without a password. A user is implicitly signed off if the transaction suffers a TERMERR condition while attempting to send data to its principal facility. However, the user is not subject to USRDELAY but is signed off immediately. If SNSCOPE is in use, the scope will be released at the time of sign off. If the transaction handles the ABEND, it continues running as a non-terminal task with the authority of the starting user.
