Hi All :)
Ok... I think someone (Maybe Ragu?) has said this already... but I
personnally always use multi pass techniques to do this...
Why? because Mike Shumko and Paul Gobes taught me to??? at least I
think that is the reason.... even my wife wonders why I do some of the
things I do when it comes to computers! hehe
Try this idea... remember that by using temp files your clean up is done for
you by the operating system when you either log off or your job logs off.
Extract from file 1 to temp_file_1
Sort on key
Extract from file 2 to temp_file_2
sort on key with same name
Extract from file 3 to temp_file_3
Sort on key with same name
Link temp_file_1 to Temp_file_2
output link file Temp_Link_file_1
Link Temp_Link_File_1 to Temp_file_3
Output to Final_file
Art "who knows... it might work? hehe" Bahrs
