scheme-sandbox

[Mark Mathias]

I've taken up Jean Abou Samra's invitation to develop my understanding of Scheme through the scheme-sandbox. I'm on Windows 10 with Guile 2.2.7 in a command prompt window. The command prompt looks correct: 

scheme@(#{ g100}#)>.

I hit a wall right away. When I type "42", Scheme should print "42" back according to Jean's tutorial. Instead I see:

 

While compiling _expression_:
In procedure bytevector-u64-set!: Value out of range: -149659645

Typing ",help all" hasn't given me a clue for what to do next, nor has a web search turned up something I understand.

Thank you in advance. I really enjoy LilyPond and the community connected therewith.
