Hi John, Not sure what your situation is, but Ed Jaffe is quite right, the compression described in that manual is pretty awful from compaction and efficiency standpoints, and maybe the API as well, I don't recall.
If you need a good x-platform data compression library that runs on z/OS, Linux, Unix, Windows, and others, you can't go wrong with zlib. It is what IBM uses for their zEDC compression adapters, and is the software behind the curtain for the z15 'Integrated Accelerators'. In addition it is extremely well supported by the authors, Mark Adler and Jean-Loup Gailly. The home page can be found at... zlib.net HTH, Mike -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Ed Jaffe Sent: Saturday, July 25, 2020 12:45 AM To: [email protected] Subject: Re: Where is the data compression manual SA22-7208 Caution!
