Dear SAS-L-ers,

Jeff Voeller posted the following in a thread that I just discovered:

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!
