Note
IBM® recommends that you use record type 30 rather than record types 4, 5, 20, 34, 35, and 40.
Record type 40 is written when an unallocation, concatenation, or deconcatenation request is processed. For an unallocation request, this record contains a device entry only for the data set unallocated. For a concatenation or deconcatenation request, this record contains a device entry for each DD entry.
Record type 40 contains the job log identification, user identification, step number, functional indicator, and device entries. Each device entry consists of the device class, unit type, device number, and execute channel program (EXCP) count for the data set.
For more information on EXCP count and CPU time, see EXCP Count and CPU Time respectively.
