Thanks Carl. But scm_apply_1 would require an additional arg1, which I don't have/need. I'm just looking to replicate what this would do in Scheme: (define this_layer (list 1 2 3)) (apply max this_layer) ==> 3 -- Mark Knoop _______________________________________________ lilypond-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/lilypond-devel
