Re: Process two files simultaneously

Thanks for your reply, Ed!

The old.csv has numerous lines like this:

AAA80008	Automobile fins		AAA	CS	0


the replacement csv has lines like this:
AAA 	Archies Automobiles and Airplanes


so by replacing the AAA in the record of old.csv we end up with:


AAA80008	Automobile fins		Archies Automobiles and Airplanes	CS	0

Thanks!
