It works (((: thank you

I have defined two convenience functions:


(define parts-length
  (lambda (parts)
    ((primitive-array-length
      <org.outerj.daisy.repository.Part>)
     parts)))
(define parts-get
  (lambda (parts k)
    ((primitive-array-get
      <org.outerj.daisy.repository.Part>)
     parts k)))

to access that array

With best regards,
