Hello Adrian, as Aaron said there are some arguments to defining functions to give access to the parser and the layout that have been made optional since 2.20. That being said, 2.18.2 is now nearly 8 years old. Unless there is a good reason for the old version consider switching to a recent version. In these 8 years Lilypond has gained a lot of functionality, improvements to existing functionality and bug fixes while also making the language easier to work with.
