      from the introduction to TINWHISTLE BASIC                  Screen 8   
    
     you're  at  it, bring me an apple" are the interactive statements, Harry  
     coming back with an apple in his hand, after having closed or not closed
     the door and having opened or not opened the window is the return.
          These statements are rendered symbolically, the symbols having been 
     previously defined by the idiom of the language and by the  architecture 
     of the machine. Some of these symbols we can change to suit our purposes; 
     others  we cannot.  As you can see by scanning the exercises, each state- 
     ment is known as a "line" and in BASIC is flagged by  what is known as a 
     "line  number", usually  but  not  necessarily  in even intervals of ten. 
     This is characteristic of interpreted  BASIC  (but  not  necessarily  of  
     QBASIC), and while  some  maintain  that  the numbers are excess baggage, 
     I prefer to think of them as  training  wheels, to  be cast aside if and 
     when our skills become intuitive.
