Notes on Homework 6.
Here is what you need to add to the-grammar for the
cond question:
(expression ;;; PROBLEM 2
("cond" (arbno expression "==>" expression) "end")
cond-exp)
and you'll have to add something along the lines of
(cond-exp (test-exps conseq-sexps) ;; PROBLEM 2
… )
to eval-expression. The form of
a cond in our language would be something
like
cond zero?(x) ==> 26 (sometest v) ==> 99 end
There were some typos in Homework 5.
These are fixed in the current copy.
Thanks to Steve Dinis for catching these.
Update: Exercise 1b also has been patched.
Thanks to Kim Chiu for this one.

Due date of homework 3 extended to Feb. 15
Since a number of people are having trouble on this one
and since I am out of town until Thursday, I pushed the
due date of this back a week. So, you have plenty of
time to go seek out help from Paul. See you next week.
