Go ahead, link the whole list, then delete the previous entry of the first and the next entry of the last.

LinkFoo 


for my $fileindex (0..$#filenames) {
  $next{$filenames[$fileindex]} = $filenames[$fileindex + 1];
  $prev{$filenames[$fileindex]} = $filenames[$fileindex - 1];
}

delete($prev{$filenames[0]});
delete($next{$filenames[-1]});

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
