Anyone care to > restore my sanity? I think you're trying to write the same file "startlu" from 2 different streams, so that's probably not what you want. And merging the matched records and unmatched records in a single stream does not make sense because the lookup would not serve a purpose... but in general you could do something like this: .. | k: nlocate .. /* divert key records */ | i: faninany | buffer | x: lookup .. detail | y: faninany | > output file a \ k: /* prolly key records */ | z: nlocate .. | i: /* but not these */ \ z: /* really keys */ | x: | insert , not found , after | y: Depending on the order of the records (if the key is before each of the details that match it), you might also enjoy feeding the keys in the tertiary input and avoid the need for the buffer stage. Another interesting approach could be to use 'autoadd' (which will reject the first one with that key, and match subsequent ones) and then inspect those rejects for being proper masters. Does that make sense ? Rob
