List of scores for book function

[Pierre-Luc Gauthier]

Hi there,

I'm trying to pass a list of scores to a book generating function and
I have a few questions.
Please see example post scriptum.

How should I structure (syntax) my score list?
I did some trials and (only) errors…

How should I iterate over said list?
I'm not quite sure how to "unfold" the score if that makes any sense.
I am using (display (car score-list)) just to figure out what is going on.

Good day
