Thanks for all the comments from everyone. They were useful, relevant, and confirmed what I guessed. I built a new PDS/E Library and planned to pick it up as each LPAR was IPLed. In the end, the Compress while in use was enough. The free space should last until after I retire, again. This group is great! Thanks again, Out.
