Sue:

I had no problem with CVTDIR. It zipped through to completion in minutes on a 
model 250. I mentioned it as a possible "irritation" primarily because I have 
no way to know what it'd run like on someone else's system. And because it was 
relatively quick and painless and I was clearly going to be in restricted state 
anyway just doing preparation for the upgrade -- applying previous PTFs *PERM, 
etc. -- it seemed an ideal time to get it out of the way.

Of course, I also had to contend with pre-GA cume packages where I had zero 
experience with what would happen when the upgrade finished. Past object 
conversions would take days to complete on some systems. Good to know this one 
is relatively minimal.

Finally, I certainly agree that RCLSTG is minimal probability. I also know 
(from past experience) that if _anyone_ is gonna be the unlucky one to get hit 
with need for it, it'll be me. (And I wouldn't be surprised if there are a few 
others who feel the same about themselves.) Now, if IBM wants to _guarantee_ I 
won't need RCLSTG for some period of time...<g>?

More than anything, I wanted to get more people reviewing the Memo to Users 
ahead of time. This document is invaluable for each upgrade. A lot of list 
members know this, but there are always new ones.
