Code will never "fall into" a function.  The code in the function will 
only be executed when the function is called.  However, you are correct 
in that most programmers put functions at the top of the page.  Maybe a 
leftover from early C, or maybe because people just want to get it out 
of the way :)

And Twayne doesn't want my help, so I'll stop here.
