CA-1 Tape Management user exits, TMSUXnA and TMSUXnS, provide the capability to bypass or modify existing ACP controls. A review and evaluation of exit code must be performed to ensure that the integrity of the CA-1 processing environment is kept intact. Unauthorized usage of these exits may compromise the confidentiality and integrity of customer data.
