OK, we also need a function which can find the total number of tunes in
the tune book (ie find the last X:). Also another to very the tune book
is in good shape (are all X: markers in order). I think you'd just pass
the tune number rather than the tune marker (X:) as that is a detail for
the parser.

Agreed. I use the Microsoft DbgHelp library a lot. You are forced to use
Callbacks for shedloads of stuff, much of which (in my opinion without
knowing the datastructures involved :-) shouldn't be necessary. Even to
find out the number of symbols you have to iterate all the symbols via
the callback. Totally crazy - anyway I wasn't advocating that, I
would've asked for a separate function
        unsigned int numTunes().
