 You are right Rob.  It was Input/full, not Input Primary.

If he is looking for blazing performance my suggestion would be to drop the
use of the join logical and go with IP and IS files with matching record
logic.  So far I have seen nothing that comes close to matching that for
performance.

Booth,

Was that blocking on a Primary file, though?

I've found that using a Primary file (where applicable) is an astounding
increase in performance.

NBRRCDS(3)?? a very small file?

What is it you are looking for? Performance improvements? Have you taken
out the K?

My experience with Block(*yes) was a revelation. It provided close to 70%
reduction in processing time in two different applications. I was
astounded

the same file, which will be effective ?
3) Which one is beneficial.

thank you in advance
