The thought process with this is you have the INFILE being updated every ten minutes lets say. So in the while loop you would read the record of the INFILE. Find the last record in the INFILE that was processed in another file called fileB. Create a new list called OUTFILE that captures the new files that need to be updated in fileB that was not processed after the last update of INFILE.

Hope this explains more.
