This is working for sorted files only rt?
because that' s the normal logic for matching
but i dont have sorted files can u please tell me for unsorted files
well... You are out of luck then,
sort the files before trying to match them
use a bit of logic puleez...
if the files are <not sorted> how will You determine a match between the first record of the first file
and the 10000000th record of the second one ???
