You can obtain records from the logrec log stream by writing a program that uses the IXGCONN and IXGBRWSE system logger services to return log data. The data returned by the IXGBRWSE service for the logrec log stream is mapped by the IFBLOGLB data area. (See z/OS MVS Programming: Assembler Services Guide for information on using system logger services.)
Note that the logrec log stream output from the IXGBRWSE service contains an individual log stream record. However, the log stream record actually contains a group of records. The logrec log stream record is mapped by the IFBLOGLB mapping macro. Fr information on the IFBLOGLB mapping macro, see z/OS® MVS™ Data Areas in z/OS Internet library.
