 <h5>Overview:</h5>

 <p>The function type can be thought of as a function signature.  It
 consists of a return type and a list of formal parameter types. The
-return type of a function type is a scalar type or a void type or a struct type. 
+return type of a function type is a scalar type, a void type, or a struct type. 
 If the return type is a struct type then all struct elements must be of first 
-class types. Function types are usually used to build virtual function tables
-(which are structures of pointers to functions), for indirect function
-calls, and when defining a function.</p>

 <p>The '<tt>ret</tt>' instruction is used to return control flow (and a
 value) from a function back to the caller.</p>
 <p>There are two forms of the '<tt>ret</tt>' instruction: one that
-returns a value and then causes control flow, and one that just causes
