Hi Leif, The efficiency of a particular sorting algorithm is very dependent upon how sorted the data is. With ten million records I imagine that might be hard to determine. FMTDTA is generally pretty good though if you need the records physically in the sorted sequence. Creating a key would probably be faster if you don't.
