   The code below writes 5 words to memory at 0x37000. I verified the words   
   are there using code not shown (for simplicity), but it's easy to see   
   that the words should be there. After that the 2 lines:   
      
      
   	mov si,3   
       	mov ax,word[fs:si]   
      
   should put dd66 in ax register but instead it puts a byte from each of 2   
   other words in ax, specifically 77bb. The routine at the end prints the   
   result 77BB when it should print DD66.   
      
   I have a situation where I really need something like this to work. How   
   can I do it?   TIA.   Bill S.
