I am currently taking a class on Perl at College, but I have found a use for it at my job. The Unix box I am currently working on has Perl 5.005_2 loaded on it. Does this version of per support back referencing, (e.g. when I put () around a part of a regular expression, it stores as $1, $2... ). Sorry if this doesn't make sense or if this is a stupid question. We literally just started regular expression last night in class.
