[Gambas-user] Accessing the nth item in a collection

[Jussi Lahtinen]

If I remember correctly Benoit warned that collections doesn't necessarily
keep the items in order. But I don't know what would make it to lose the
order. Maybe he will enlighten the issue.
Anyway I suggest you use array of objects, which you declare extra property
"Key".
