[Bug-mit-scheme] small glitch

[Mike Wiley]

Hi I am new to programming. I am using Scheme and Art of Programming book. I 
have come across a small glitch with the function ctrl x z...the line by line 
programming testing window. I put in (define Robert 'Bob) and gave the value 
robert. And when you call that value Robert it says the value is bob. which in 
the book bob should is Bob.
