So no one knows how to do this without a while of 20K records (fileB) with another 200K records (fileA)? Would be even better if someone knows how to just work with fileA and for each record in fileA apply the highest value in col4 to all records with identical first 1-3 columns (key) since that's all I'm using fileB is for right now.
