SETS and ROLS call log records

The SETS (X'30' subcode) and the ROLS (X'34' subcode) call log records are written whenever an application that might cause data to be captured issues a SETS or ROLS call using a token.

The log records are written to indicate that any changed data log records written after the SETS call for the token used in the ROLS call will have been aborted (backed out). The records are written even if exits are defined without a logging request.
