How to change printing behaviour in DrRacket for R6RS to print results like with #lang racket

问题

When I'm running a program in the IDE, version 5.3.5--2013-06-18(-/f), for #lang racket, eg.

#lang racket

(+ 4 5)
(/ 10 2)

When pressing Run >, the interaction window gets "9\n5\n" printed to the interactions window. The same version as R6RS

#!r6rs
(import (rnrs base))

(+ 4 5)
(/ 10 2)

It seems I get no output when pressing Run > when language is R6RS. Is there anywhere I can change this behavior, in Preferences perhaps?
