This is the end result I have in mind. What I need is a map of the connection between the two arrays. The arrays represent a certain set of tokens in two different files. What I want is very similiar to doing a diff between two files, except I don't want it on a character by character basis or a line by line bases, I want it on a token by token bases where a token matches m/(\w+|\S)/. What I need the map for is not important (well, it is to me, but I already know that I need it for what I am doing). In response to your other question, "How are you to determine that "burritoes" (sic) is a replacement for "tacos" ?", I would determine that the same way that I would determine "a" is a replacement for "e" in the between "tall" and "tell". The algorithm would be something like "IF everything in sequence A is the same as everything in sequence B except for the token at index N, THEN token B[N] replaced A[N].
