John, What system? If you are on UNIX, I'd use the external "sort" command to sort my data, then use the "uniq" command. Much easier than using Perl, in my opinion. sort <input.file | uniq >output.file I can't help you if you are running under Windows. I don't think it has a "sort" or "uniq" command. If you need to process the records in Perl, I would most likely do: sort <input.file | uniq | myPerlProgram.perl -- Maranatha!
