Hi David,
\test apparently expects a string argument.
Aaargh, sorry, stupid me, and stupid copy'n'paste error. So, another try:
\version "2.19.82"
test = #(define-scheme-function (suffix) (string?) #{
\book {
\bookOutputSuffix #suffix
\score {
d4
}
}
#} )
\test "surname"
(still) causes a "Bad expression type" error.
