   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.

Scheme syntax is case-insensitive -- or, specifically, case-folding.
So there is no difference between writing

(define Robert 'Bob)


(define robert 'bob)



You can make case significant by setting the parser variable
*parser-canonicalize-symbols?* to true (e.g., scmutils does this for
writing classical mechanics notation in Scheme).
