in thread recursive difficulty

That seems not to be working for me, despite using ^V. I think it is my vim expandtab setting. I tried pipes as delimiters, but split /|/ seemed to split between characters for some reason:

ch: v, par: e
in my little debug printout.

I am a litttle baffled.

    The first argument to split is a regex, not a string. /|/ says to match either nothing or nothing. Split, as documented, will split every character when giving a regex that matches nothing.

    theorbtwo answered your problem with split /|/, I suggest that you use the magic split ' ', $line or if working on $_, simply split. This splits on one or more whitespace and ignores empty fields (because of spurious whitespace) at the start and end of your line which should work best in your case.
