A primary objective / benefit here is reduced CPU-consumption (and likely reduced IBM/ISV cost) on the IBM z System general CP...consider a VOTE-UP!!
WPS software on IBM z/OS has the ability to invoke zEDC data-compression as an API-request, not only with SMS-managed sequential-format output file though (i.e., invoked internally, in addition to DATACLAS). The size-reduction observed with other types of zEDC-compressed data algorithm is anywhere from 60-80% which is substantial, while offloading the CPU-consumption from the general processor.
And consider the CPU-consumption for this type of alternative data-compression is executed as an external card/feature and not as a general CP function, thereby not contributing to the overall 4-hour rolling-average MSU consumption, used by IBM and ISVs to charge clients.
For these observations, World Programming is strongly encouraged to explore IBM z System (mainframe) zEDC data-compression feature as a cost-effective alternative to the current-standard CONFIG/OPTIONS COMPRESS= functionality.
