OK, now that I've got my nested feedback loop working, I think I could use some advice along these lines for collecting the nonmatches. At the bottom of the cascade, I now send the nonmatches back up to the top. At some point I want to pick out the ones that *never* match. My first thought was to use LOOKUP AUTOADD and send back the ones I hadn't seen before, and keep the ones that came out a second time. But remember, I'm also using NOT LOOKUP AUTOADD to discard duplicate input in each of my inner loops. So nothing will ever come out the bottom twice! So I guess I'll just need to put the nonmatches and matches into one more LOOKUP to find what's never matched. But am I overlooking some way I could use the various alternate inputs of LOOKUP to do that more efficiently than just buffering the whole mess? Would it help me any to make the primary output of the LOOKUP AUTOADD in each inner loop available? ¬R
