One type 66 record is written for each record written or deleted from a catalog.
Record type 66 identifies the entry being altered and the catalog in which the catalog record is written or deleted, and gives the new, updated, or deleted catalog record. It indicates if the entry was renamed (function indicator = ‘R’) and, if so, gives the old and new names of the entry. It identifies the job by job log identification and user identification. The job name, time, and date that the reader recognized the JOB card (for this job) constitutes the job log identification. If a system task caused the record to be written, the job name and user identification fields contain blanks and the time and date fields contain zeros.
