Yes, you are.  Control flow can also "drop though" when executing the 
paragraphs.  In any other language, you'd have to invoke the paragraphs 
explicitly.


Thus:

Para-1.
    ...some code...
Para-2.
     ...some more code...
Para-3.
      ---yet more code...
Para-4.
      ...and some other code...


If control flow proceeds normally (or via a GO TO) to Para-1, control 
will normally flow from there out the bottom of Para-4.
