编写程序完成10个数的求和：SUM=a1+a2+.....+a10;
DATA  SEGMENT
     BUFFER  DW  1,2,3,4,5,6,7,8,9,10
     SUM  DW  ?
DATA  ENDS
STACK  SEGMENT
     DB 100 DUP(?)
STACK  ENDS
CODE  SEGMENT
     ASSUME   CS:CODE, DS:DATA, SS:STACK
START:
      MOV  AX,DATA
      MOV  DS,AX
      MOV  AX,0
      MOV  DI,OFFSET SUM
      MOV  BX,OFFSET BUFFER
      MOV  CX,10
LOOP1:
ADD AX,[BX]
      INC BX
      INC BX
      DEC CX
      JNZ  LOOP1     
      MOV [DI],AX
      MOV AX,4C00H
      INT 21H
CODE  ENDS
END   START

问题补充：
知道DOS调用，我不会写，出来的是乱码，就是DOS调用具体怎么写啊！？

顶啊 ，有人帮忙吗

呵呵，谢谢啦，大哥
