Add $|++; at the top of the program.

    Thanks! Seems so simple and it works!

    Now, I do have a non essential quest for knowledge....why did it work on V5.6 but no V5.8?

      why did it work on V5.6 but no V5.8?

      The rules regarding automatic flushing of the STDOUT buffer changed from perl-5.6 to perl-5.8. Setting $| (or incrementing it from 0 to 1, as per BrowserUk's approach) is the way to make sure that the perl-5.8 STDOUT buffer gets flushed in much the same way as happened automatically with perl-5.6.

      For a simple demo of the difference, the following outputs hellogoodbye on 5.6, but goodbyehello on 5.8: 
      perl -e "print STDOUT \"hello\";print STDERR \"goodbye\""

      Setting $| will ensure that hellogoodbye is output on both 5.6 and 5.8: 
      perl -e "$|=1;print STDOUT \"hello\";print STDERR \"goodbye\""
