$# is the highest index of an array, see "length of an array" in perldata (or perldsc for examples)

and please use <code>...</code> tags around your snippets when posting.

  • 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.
