Error message Unbound variable %

This error message will appear at the bottom of the console output or log file together with a “GUILE signalled an error …” message every time a Scheme routine is called which (invalidly) contains a LilyPond rather than a Scheme comment.

LilyPond comments begin with a percent sign, (%), and must not be used within Scheme routines. Scheme comments begin with a semi-colon, (;).


LilyPond — Usage v2.25.8 (development-branch).
