Lab 7

This lab will focus on data-directed programming.

Exercise 2.77 from SICP

Download the lab06support.scm file from the lab section of the website. Load
it. Then install the three packages (how?). Then do exercise 2.77 from the text.

Note that the questions require text answers, not code (the code is given in the question).
Note that the implementation for the operator table and the put and get operations on it is in this file, but you can (and should) answer the question without understanding the implementation. [We will cover the implementation of the put and get table in the next few weeks].
