The data collection record is a fixed-length header for all the record types. It contains all the common fields that are needed regardless of the type of data collected. All other output record data is appended to the header.

The data collection record header is available in SYS1.MACLIB(IDCDOUT) provided by DFP Version 3 Release 2.0 (or later) and by DFSMSdfp.

You may access all data collection record definitions (including DFSMSdfp-specific records) in a program written in assembler language as follows: ARCUTILP IDCDOUT=YES.

If you wish to define only the header and DFSMShsm-related records, use: ARCUTILP or ARCUTILP IDCDOUT=NO.
