David, Right. Thanks. I know my mistake now - from reading the guile page, I thought eqv? should work for characters. However I should have used string=? since the variable is a string.
The display function is a real life saver. Not only is it easy to spot mistakes, it also makes it a good way to experiment new things. Jay _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
