Values can be subject to fixups, so in the general case you can have
expressions with references to other (external...) symbols. And AFAIR
multiple fixups can be applied to the same location, ending up in more
complex expressions.


IMO you should become more familiar with COFF files first, so that you know
what you may encounter there, besides simple numeric values.
