Hello there. Here is my problem. In one file, we'll call
file "A", there is a list of lets say 100,000 phone
numbers. Now in file "B" there is a list of 50,000 phone
numbers, some may match those is file "A" and some may
not. I need a way to combine those two files and have
only the numbers in file "A" that didn't match with the
numbers in file "B" go into some sort of group of their
own. Is this do-able??
