C311 Assignment 12 -- Parameter Passing

Due Monday, April 8, at 9 AM

Submit via email

Extend the code in call-by.ss to add call-by-need and call-by-value-result parameter passing. In particluar, you should define the procedures call-by-need and call-by-value-result which, when applied to no arguments, will change the behavior of the interpreter.

In addition, write an expression that returns a different answer in each of the five parameter-passing mechanisms. Bind this expression to the variable test-case:

> (define test-case 'exp)

Submission

Write your answers to the exercises in a file (with comments, following the proper indentation rules), and send that file to

c311@lakshmi.cs.indiana.edu

with the subject line

12

Assuming you've saved your homework in the file ``asgn.ss'' in the current directory, one way to submit is with the command:

Mail -s "12" c311@lakshmi.cs.indiana.edu < asgn.ss

remember to include the line

(load "record.ss")

at the beginning of your file.
