If you want to use "message" again, you just... use it again. You don't need to clear its previous content first, that can be overwritten.

But if you really want to wipe a variable's content (which can be useful in the case of table indexes):

message = nil

Note that all local variables are generally auto-wiped when the block they were defined in ends.
