That definition helps. I use the Guile manual, the section Regular Expressions is miss leading about what is there. I only went there because Arron Hill told me about it And the introduction states "A full description of regular expressions and their syntax is beyond the scope of this manual"; and the URL goes nowhere. And I would guess knowing what to read elsewhere that is consistent with the guile version Lilypond uses may be a probleblen. I am open to a good ron cryptic reference? Thank you, ƒg > > JM > >
