Question sous-chaîne de Flash Lite 1.1

Question

Pourriez-vous me dire pourquoi les deux lignes affichent a?
trace(substring("asd", 0, 1)); // == "a"
trace(substring("asd", 1, 1)); // == "a"
(cette imprime s:
trace(substring("asd", 2, 1)); // == "s")

Est-ce que dans Flash Lite 1.x l'index départ avec 1?
