/**
    This class is for representation of object code
    for translated function blocks in the simulation 
    of Assignment 2, CS 152, Section 4, Fall 2005.    
    
    Use of the block naming facility is optional.  It 
    may be useful for debugging.
    
    Since the class is abstract, it needs to have 
    subclasses.  It is acceptable to have more than
    one subclass, some of which implement the 
    <code>execute</code> method trivially.
