Hi Dave and others:
Having worked for Wally many years ago at Unidata, his knowledge
is unparalleled about Unidata. So given that I've been doing this for a
number of years, I'm not sure where the 100 number is coming. The other

I wouldn't go below 10%. You could end up with lots of splitting and

Hi Dave:
You cannot get any lower than one percent. If you set your block size to
2K that will fix the split problem making about 6%. Your average record
size is 1537 which means you will get about one record per block so split
by key will be worthless and you will be into Level 2 and/or Level 1

I've only got a handful of dynamic files but of course they're huge and
have a big impact on our daily and monthly processing. I'd REALLY like
