In addition to using a "last" in a while loop - which is not good practice, this solution goes against the spirit of the OP's question.

    Well it made me laugh, especially as the "spirit of the OP's question" is obviously homework. :)

      (drifting off-topic...)

      It was actually useful for me, even though it's not a homework assignment :)

      I wanted to send the results to a file (not a problem), but this syntax caused a space to be inserted at the beginning of the second and subsequent lines. I'm already generating the array elements with a terminating newline, so I had to use:

      print FILE join( "", @array );

      To get what I wanted.

      Thanks though, for helping me to think outside of the looping concept.

        Why join? If you're already generating the array elements with a terminating newline, why not just:

        c:\@Work\Perl\monks>perl -wMstrict -e "my @ra = (qq{bat\n}, qq{ball\n}, qq{glove\n}); print @ra; " bat ball glove
