Again I think there is a confusion.  The program I have written compiles
correctly BUT the output of the program in not desirable.  Here is a
test:

1. Load "ambeval.scm"
2. Type (driver-loop) into your REPL session.
3. Copy and Paste following snippet:

   (define (findout32 x)
    (letrec ((even?
	      (lambda (n)
		(if (= n 0)
		    #t
		    (odd? (- n 1)))))
	     (odd?
	      (lambda (n)
		(if (= n 0)
		    #f
		    (even? (- n 1))))))
      (cond
       ((even? x) 20)
       ((odd? x) 30)
       (else 40))))

4. Type (findout32 10)

Output/Error:

;;; Starting a new problem ERROR: In procedure scm-error:
Unassigned variable -- LOOKUP-VARIABLE-VALUE odd?

Expected Output:

20

All the best,
Utkarsh Singh
