Jeff, I also noticed that the Raithel book, Tuning SAS Applications in the
MVS Environment, discusses FREE=CLOSE in Chapter 8. Those persons lucky
enough to own a copy of said book can RTFM and find it in the section
titled: Freeing Tape Drives When Done With Them.
Jeff, best of luck to you as you explore and utilize obscure OS/390 options
to make your SAS applications more efficient!
I hope that this suggestion proves helpful now, and in the future!
