Hi Arthur,
I need a list of lists because each line has more than one number. You

Although I can't imagine why you'd need it, but in order to get list of

(let ([p (open-input-file file-name)])
(let f ([x (read-line p)])
(if (eof-object? x)
Hello,
I'll be in Nuremberg from Friday noon to Sunday noon. I'm fine with the

(45,60€) beds respectively. Please contact me if you're interested in
sharing one
