[AUCTeX] automatic insertion of labels

[David Romano]

Two questions, really:

1) When I use TeX-insert-macro to insert "\label", I get the message
"Symbol's function definition is void: nil" instead of being prompted for 
an argument.  Is this normal?  How can I change this so that I am prompted 
for an argument?

2) Is is possible to have labels automatically inserted for theorem-like 
environments the way they can be for equation-like environments?  I 
haven't been able to find out what the corresponding variables might be.

Thanks for your help,
David Romano
