EndOfFile

Math Groupers,

Somebody explain Read & EndOfFile to me, preferably using  
monosyllables and diagrams.

My code looks like this:

While[(headline = Read[file,String]) != 10,(
	statement;
	statement;
	)
];

And it works fine.  It reads the lines and processes them and the  
loop terminates when at EOF.  However if I change != 10 to
!= EndOfFile it fails to run.  Why?
