Hi gingaloon if you have 12345 then the sequences of two digits are 12 23 34 45... HTH - Mark Update: my (guessed) explanation as to why you don't get what you want is that you're not modifying the pattern "in-place", so to speak, so the regexp engine doesn't take account of the changes it makes. This is one use for backreferences (\1 \2 \3) Update 2: why not just s/(\d\d)/$1\n/g?
