Add a line like: (bake "apple") The define form defines a procedure, but nothing happens untill that procedure is called. Jos

Hi, I am wanting to both print something and do something. I found an example in the Racket guide p.20 sec.2.2.1 Only nothing comes back in the interactions. It runs fine - no errors, but appears to do nothing. Both printf and string-append are suppose to be in racket and racket/base. Any ideas? Thanks, Carolyn The code: (using Racket ver.5.1.1) #lang racket (require racket/base) (define (bake flavor) (printf "pre-heating oven...\n") (string-append flavor " pie"))
