in thread for mistake with shift

Yes! I like that version, it does exactly what I want without the overhead of the duplicate array. I wonder if while (shift(@text)) { wouldn't work as well? Thanks!

    To answer my own less than bright question, Yes, but then the unshift would have to be outside of the loop. Something like:

    while(shift @text) {
  # do whatever...
}
unshift(@text,'') if @text;

    I Think I like the while (defined (shift @text)) { better.
