This might work but it would be more difficult without regexs - the
current application does a system call to agrep but of course it is very
slow for large numbers of calls.  A typical call is something like:

	agrep -2 "Smith\|J.*12345" list1.txt list2.txt list3.txt

This allows two differences on a minimum amount of information
consisting of last name, first initial and zip code.  If I use the
Enumerable version, I would have to use the whole, delimited, name &
address string and increase the differences/distance number?

Did you just do that hack now? - how do I get/install it? (Fedora 8).

Thanks,

Phil.
