You had fun composing that, didn't you? Actually, it's not a situation that happens very often (except on this list) - only when you are writing about abc itself, and illustrating what you say by means of examples. I have to be careful when writing BarFly's documentation, which consists of abc files containing tutorial text with example tunes. Since BarFly absolutely insists on having an X: field at the beginning of a tune , all I have to do is to avoid what I've done in this sentance, i.e. putting the characters X: at the start of a line. Not that that would kill the parser, of course, just display an error message where the music should be.
