Awesome, that worked. I'm still confused as to context; was I treating it as a scalar? I looked through help file for split, but I guess I don't understand the difference.

Anyway, I've got it working. Thanks for the advice!

    About variables and context, see pelrdata

    $list=split ...: 'split' in scalar context because '$list' is a scalar value (split: In scalar context, returns the number of fields found.)

    @list=split ...: 'split' in list context and returns a list because '@list' expects a list value.
