The SYMREC macro updates a symptom record with system environment information and then logs the symptom record in the logrec data set or logrec log stream. The system or application, using the SYMREC macro, creates a symptom record. The ADSR mapping macro maps the symptom record, and the symptom record contains diagnostic information determined by the application.
As an application or a system component detects errors during processing, it stores diagnostic information into the symptom record and issues the SYMREC macro to log the record. The diagnostic information consists of a description of a programming failure and a description of the environment in which the failure occurred.
See z/OS MVS Programming: Assembler Services Reference IAR-XCT for information about the SYMREC macro. See z/OS® MVS™ Data Areas in z/OS Internet library for information about the ADSR data area.
