I don't know why you think I assume that the manual writers are
incompetent - I don't assume any such thing.
I asked why I might be getting the error. And you have kindly answered
my question, even though it appears that I inadvertently irritated you
to some degree.
The fact is that, yes, the score in question was accessed in a \book
section in another file. I was not aware that I couldn't use
showLastLength inside a \book { }.
In the mean time, I got around the problem by using
Score.skipTypesetting instead. I was getting a warning about a hairpin
being too small, with of course no indication of where in the score it
might be - tricky in a 150-page score. I eventually tracked it down.
Thanks for your help.
