Thanks, Harm! Sometimes it's almost as good to be lucky as to be good.
You are absolutely right, of course, and were I not too lazy to do so, I'd
have looked up the line where the actual error was. Instead I just saw
that #f didn't work, so I changed to "",
Also, Mike, while my comment about \define always going at the top level,
that same thing is NOT true in general for functions of the form
\defineXXX. I can't think of any cases where it causes problems to put
them at the top level. But it's not strictly required, and the use of
\defineBarLine inside the music expression was not the cause of the errors.
I just wanted to clear up my possibly confusing statement.
Thanks,
Carl
