in thread Regex to find URLs in a string

i don't think that $#newline means what you think it means. that variable indicates the index of the last element of @newline (if it is non-empty) and has nothing to do with the scalar variable $newline.

try the following instead:

if (substr($newline, -1) eq '.')

    Thanks for the correction. I've learn most of my PERL by guessing. I figured if $# worked for arrays, it might work for scalars.

    Your suggestions is also, I find, a lot clearer and more percise. Thanks.
