Transaction accounting record (TAR)

The field structure for detail and summarized records is identical. Summarized records simply combine, in the corresponding field, all individual fields within detail records that can be treated as accumulated values. For values such as core allocated and core used, the summarized record contains the high-water mark.

Each transaction accounting record is divided into two areas, a fixed-data area and an area that contains a variable number of fixed-length segment types (trailers).
