title: sbyte smallest signed byte?
body: <p>In the book assembly_language_for_x86_processors by kip irvine he writes</p>
  
  <p>val4 SBYTE -128  ; smallest signed byte.
  var3 SBYTE  127  ; largest signed byte.</p>
  
  <p>I thought that the first bit is the sign bit.  So should the smallest byte not be -127?</p>
  
  <p>Any help would be greatly appreciated.  </p>
