Bonjour, For having the stack trace you need to use the errortrace library http://docs.racket-lang.org/errortrace/.
If you run drracket you can activate it or not when you choose the language. If you run geiser you can put "(require errortrace)" in ~/.racket-geiser. If you run from the command line so "racket -l errortrace my-script.rkt" will show you the stacktrace. ____________________ Racket Users list: http://lists.racket-lang.org/users
