Re: How to retrieve the data compression method of a save file?

Yeah, that makes sense. Personally, I always use *MEDIUM. Several years ago tried all the options and found this a happy "medium" (sorry) as to size and time to do the save.

But this would be something the OP could nicely use for justification. Hope he takes one of the pathways to asking for change.

Vern,

One benefit might be to audit "long term" save files and beat those into
submission who do not use the higher compression ratios. Sure, there's a
performance hit, but for long term, rarely accessed save files of a
considerable size, it's worth it.

Sent by: "MIDRANGE-L" <midrange-l-bounces@xxxxxxxxxxxx> To the original poster - there has to be something in the SAVF that would tell you this. SAVFs can be read record by record, and there might be something in the OIR of the object. Still, I am curious to know what the benefit of knowing this is. If you were to submit a requirement at COMMON or submit a DCR, you would need to justify the cost of doing this by IBM. Regards Vern On 2/10/2016 6:24 AM, rob@xxxxxxxxx wrote:
