<P>Executable code (statements, control-structures, variables, etc.) can
be expressed as first-class objects. Such expressions can be associated
with controls to specify their actions, to method objects to specify
their implementation and as arguments to method invocation to specify
details of the operation to be performed.
<P>Executable objects are used in many of the examples in this manual.
<A class="sec" href="exeobjects.html">Section 10.2</A> provides an
overview of them.
