我正在尝试找到此阵列的AVG：1742,1065，-67，-2988，-796，-1000,31，-67，-100,1180 我相信我的方法是将数字从POS更改为NEG。我的编程需要计算上面的数组然后打印massege如果AVG是NEG或POS，它总是打印AVG是POS，即使它不是。这是我目前的代码：

; lab56.asm
;
    .MODEL SMALL
    .STACK 100h
    .DATA
AVG_NEG  DB  'THE AVG IS NEG',13,10,'$'
AVG_POS  DB  'THE AVG IS POS',13,10,'$'
INDEX    DB  'Numbers that are larger than the average are in indexes:',13,10,'$'
RES      DB  '                     ','$'
ARR      DW  1742,1065,-67,-2988,-796,-1000,31,-67,-100,1180
Ten      DW  10
AVG      DW  0
temprint DB  '      ','$'
;Program start here:
    .CODE
    MOV AX,@DATA    ; DS can be written to only through a register
    MOV DS,AX       ; Set DS to point to data segment
    LEA SI, ARR
;
;   SUMUP
    MOV CX,10       ;10 variables in array
Sum:
    MOV AX,[SI]
    CMP AX,0
    JG Pos_label
    XOR AX,0000000000000000b
    ADD AX,0000000000000001b
Pos_label:
    ADD AVG,AX
    ADD SI,2        ;move to the next number
LOOP Sum
;   Divided by 10 to get the AVG
    CWD             ; AX -> DX:AX
    IDIV Ten
    MOV AVG,AX
;   print

;   Check if NEG or POS
    CMP AVG,0
    JG Avg_label
    MOV AH,9       ; Set print option for int 21h
    MOV DX,OFFSET AVG_NEG       ;  Set  DS:DX to point to AVG_NEG
    INT 21h
    JMP continue
Avg_label:
    MOV AH,9       ; Set print option for int 21h
    MOV DX,OFFSET AVG_POS       ;  Set  DS:DX to point to AVG_POS
    INT 21h
continue:
;

;Program end's here:

     MOV AH,4Ch       ; Set terminate option for int 21h
     INT 21h       ; Return to DOS (terminate program)
     END

在计算平均值时，我应该规范化输入的符号吗？
