DECODE – Determine which fields to decode

When a segment is retrieved from HCL Workload Automation for Z, it can be automatically decoded into its separate fields. The DECODE keyword decides how much of each segment to decode.

ALL
Decodes every field in the segment definition. It takes more processing cycles but simplifies the coding of any FILTER statements that might require fields that are not in the OUTPUT statement for that segment.
ONLY
Decodes only key fields, and fields specified in the OUTPUT statement for that segment, involving much less processing. This is the default.
