Guys, please realize what I put forth works for ME, and it is up to YOU to either use it, modify it, or throw it in the trash. As it stands, it works perfectly well for its limited intended purpose in my plain-jane VM admin environment. I usually don't shoot for "elegant" or "proper" when I want it quick and functional, so I apologize for that. You can hang stuff all over it all day long until it looks like the Elephant Man, and it won't work one bit better.
Now if this were a scheduled production routine, or distributed to my 3000+ end users, or involved a few hundred lines of code, there would naturally be more optimization and checking built in. So in this case take it or leave it for what it is - just a quick and dirty admin construct that helps relieve over-taxed memory cells. Again, SFSLIST on the IBM downloads page is more polished and the one you want for prime-time use. Your critiques are well intended but I hope they don't dissuade others from posting their little tricks of the trade that we can all benefit from.
