My >answer: only inside macro definition, not in regular code, and not in >macro call actual argument. The LRM talks about how these special character sequences in a macro affect the expansion, so I would agree. >2.

My answer: it can be used with fixed text. >Thus, inside a macro definition, a``b gives you "ab" if a and b are not >formal arguments. If either or both is a formal argument, then the >actual argument is substituted, I don't see any real use for this, but the LRM text seems to allow it. It says that it delimits lexical tokens without introducing white space (a rather unclear statement), and then says that this allows identifiers to be constructed from arguments. The mention of arguments is in the explanation of how it is useful, not in the description of what it does. So I don't think it is restricted to arguments. >3. Can it be used to paste together anything or only to make an >identifier? For example, can I do <``= to get <= ? My answer: it is only >for making identifiers. Making anything but identifiers this way seems pretty strange. However, the LRM text does not appear to restrict it to this. As with the previous question, the mention of identifiers is in the explanation of how it is useful, not in the description of what it does. So the LRM does not seem to be restricting it to this. But we should probably be figuring out how to word the LRM to mean what we want, rather than trying to extract meaning from the vague wording that is there.
