When I woke up this morning my mind told me I'd goofed. What it really 
said was something like, "You IDIOT, you left out the word length, and 
worse you emphasized the wrong word."  My brain is pretty nasty before 
it gets its morning fix of caffine. ;-)

I meant to say "the Buffer contains a constant LENGTH String..."  In Ada 
83 you had to declare the String a constant for this idiom to work, but 
that wasn't what I was trying to say.  The magic is that each time 
through the loop the buffer is exactly the right size to hold the line. 
  If you need to be able to change the length of the buffer though, you 
have to use Unbounded_String.
