   That seems somewhat bogus:   
      
   If you can do Mo, Tu, We, Th etc in 40 bytes, then adding one more byte   
   to each string should only result in 7 more bytes?   
      
   OTOH, if you do all the two-letter abbreviations as two Dos calls and   
   the 3 and 6-8 letter versions with '$' terminated strings then it makes   
   more sense. :-)   
      
   For the two-letter case:   
      
   mov ah,2ah   
   int 21h   
   cbw   
   mov si,ax   
   mov dl,first_letter[si]   
   call print1   
   mov dl,second_letter[si]   
   print1:   
   mov ah,2   
   int 21h   
   ret	;; Return after first letter, exit after second   
   first_letter db "SMTWTFS"   
   second_letter db "uouehra"   
      
   Close to your own?
