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.
