STEP#

Sequence number of the step in the job creating the dataset. The format is Snn, where nn is the relative sequence number of the step from the beginning of the job. The number is in hexadecimal notation (01-FF).

FILEID

Unique file ID in the format Nnnnnxx, where nnnn represents the relative position of the file in the allocations performed by the job (in hexadecimal format), and xx is the logical extent number of the CDAM dataset (also in hexadecimal format).
