Yes, but you can get the end of chain record number (stat7-8) on the dbfind and then start reading backwards. Curt Brimacomb System Manager www.magiclink.com Idaho Computer Services, Inc.

I need to create a new Image dataset. I want to retrieve the records in reverse date order (LIFO). I was going to do a backwards chain read. Someone told me that a reverse chain read was not efficient. For other design reasons, I've decided to use a composite Omnidex key, but I'm curious if the above is true. If so, Why?
