llMessageLinked() for unlinked prisms

Is it possible to use llMessageLinked() for unlinked prisms ?

I.e.

- The object A rez the object B (which is in the content of the object A)
- The object B is unlinked and I want to change the name of the object B from a script in A

can I do this with llMesageLInked() (how?) or should I use the chat channel ?
Where can I find a guide describing how the objects should communicate by chat ?

i.e. How can I invoke an object method from en external script ?

thanks,

sorry for the post! I found all the answers here:
