   I mixed it up typing it in.   
   It should be:   
             ZYXWVUTSRQPONMLKJIHGFEDCBA9876543210   
   chars64 dq 111101111110111110111011100000000000b   
      
   and   
           VUTSRQPONMLKJIHGFEDCBA9876543210   
   chars dd 01111110111110111011100000000000b   
           ZYXW   
         dd 1111b   
      
   I use it to determine with a "bt qword ptr [chars],rax" if it is a   
   valid letter in the program.   
      
   But those 36 bits should fit into a quad.  It is probably a bug,   
   because the OP is right   
      
   hchars	dq	FBEFBB800h   
      
   does work.
