I read fine. I may be confused, but my understanding is that extern NSString* const <blah> IS an address. Also, adding the explicit & confuses the compiler - it then marks that code as dead, stating it will never be executed. I’m not sure how it comes to that conclusion exactly, but it tends to suggest that taking the address of an extern string constant is not a sensible operation. —Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
