RE: Efficient Code

Eric, don't know if you were responding to my post or both mine and Walden's 
but,
with my "would be nice to have" report needing to show the files that could 
share
the same access path, the ANZDBF* commands aren't much better than running the 
DSPFD
commands.  There'd still be (a lot of?) programming to do to put it together.  
All
the information is available in one form or another, it's just a matter of 
piecing
it together.

Walden, I didn't understand your use of indexes vs. logicals.  Thank you for 
setting
me straight.  Would you agree, then, on the need for a report the likes of which
I've described?
