Your index won't work in case there is an a before the third position, e.g. in the string aba. If you (really) want to use index, use the 3-argument-form instead: 

$x = "aba";
print "$x\n" if index($x, "a", 2) == 2;

  • 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.
