Hi Freeman,
I'm not completely sure about the internals but #(display) procduces its
output in some unpredictable manner. Sometimes, when you (display) some
very large structures it may be totally interrupted by other output (at
least in Frescobaldi).
When you want more reliable output (especially if you want to follow the
order of operations) you could rather use
mylist = #(list 'red random 12)
#(ly:message "My list: ~a" mylist)
Good luck

I am using Frescobaldi and studying the Scheme Book. When I compile,
mylist = #( list 'red random 12 )
#(display mylist)
I get two different results in the LilyPond Log, see below. The line,
(red #<primitive-procedure random> 12)
changes positions randomly when compile. Would someone explain?
Thank you, ƒg*/
