o dear, thunderbirds always destroys any formatting done in frescobaldi ...
here my working example as an attachment.

OK, copy&paste lost a paren ... but not in the let-line, but in the end of the whole function.
let opens a new "scope", so you start with a new block:
(let ((book #{ ... #})
       (something-else 42)) ; paren closes definitions
      ; now do something inside this scope using the defined vars
    (ly:process-book book ...)
) ; close let-block

This let block returns the value of the last statement:

writeScoreOddEven =

#(define-void-function (parser location score)


(let ((book #{ \book { \score { $score } } #}))

; process with first-number 1

(ly:output-def-set-variable! (ly:book-paper book) 'first-page-number 1)

(ly:book-process book #{ \paper {} #} #{ \layout {} #} myname)

; process with first-number 2

(ly:output-def-set-variable! (ly:book-paper book) 'first-page-number 2)

(ly:book-process book #{ \paper {} #} #{ \layout {} #} (format "~A-even" myname))

)) ; close let *and* define-void-function

     You can create an adhoc-book in scheme with a #{-#} construct:
          writeScoreOddEven =
          #(define-void-function (parser location score)
          (let ((book #{ \book { \score { $score } } #}))
          ; process with first-number 1
     Unfortunately this gives me the following error:

In procedure memoization in expression (let (book #)):
Try copy&paste.  You are missing one.
Huh? I'm missing one what?
Am I right that the '(let ...' line is one statement and that the last ')' in this line should match the one right before 'let'? In fact I did copy&paste, the line as above is quoted from Jan-Peter's email. But of course we're not here to blame but to solve the problem ;-)
Your example was either missing a closing bracket or having one
opening bracket too much. But that doesn't change anything.
No, you just did not understand that
; process with first-number 1
was supposed to be replaced by the rest of the function body, depending
on what you want done.
Of course I know that (the comment line was actually from _my_ file).
Attached you see the complete file.
