  • 10 September: There are a few minor changes to the ps3.zip file, if you already downloaded it (before 1:45pm Saturday), please download it again:
    • The original ps3.zip code did not include the definition of horiz-line that is in the ps3 handout. It has been added to graphics.ss.
    • Question 4b asks you do define a vertical-line procedure. Unfortunately, the name vertial-line is already used for a procedure that does something else. For Question 4b (now revised on the web version), you should name your procedure make-vertical-line instead.
