HW 16: The Runtime Environment

Read Webber Chapter 12 and do the exercises below.
  1. Webber exercises 12.2-12.5.

  2. Consider the ML program below (Example 2 from the handout in class):
    Trace the call f2 7 8 and draw  the runtime environment that
    is created, including activation records with parameterss/local variables and
    static links.  Use the rules we discussed
    in class for setting up static links and and using static links to 
    find memory locations for
    non-local variables at runtime.  Something goes wrong.  What is it?  
    Carefully explain the problem.
