Additional records in the log stream copy
When a log stream copy (DWWLC) is performed, the records in the MVS™ log
stream are copied to a sequential data set. In addition to the records in
the MVS log
stream, DWWLC writes two additional records to the output file, the first
record and the last record, both called LOGI records.
