in reply to Problems with formatting the results of my regex

I think you may have a carriage return character \r at the end of the lines in your input file. chomp doesn't remove it. So after $data with a \r gets printed the caret is at the beginning of the line and the beginning of the line is overwritten with whatever follows $data in the print statement. You can remove \r with this for example tr/\015//d;.

    Fantastic! Thanks for the quick response. I tested the new code and it's working perfectly now. I still can't understand why the \r was getting captured in $2, since that portion supposedly should end with \d* zero or more digits. In any case, I'm glad it's fixed now.

      .? in (\-?\d+.?\d*) matched \r

        Yes, most (all?) of those . characters in the regex should be changed to \. so that they match just "." not /[^\n]/. You can also use [.]

        - tye        

        Ah.... That's part of my problem then. I intended .? to mean literally "zero or one decimal points" That was a rookie mistake.
