Question

帮忙看一下汇编语言a2070错误

DATAS SEGMENT
buf db 100
db ?
db 100 dup(?)

BUFB db 100
db ?
db 100 dup(?)
string1 db "Please input 10 numbers:$" ;字符串以$结束
string2 db "There are: $"
string3 db " positive numbers.$"
STRING4 DB "The positive numbers are $"

;此处输入数据段代码
DATAS ENDS
STACKS SEGMENT
;此处输入堆栈段代码
STACKS ENDS
CODES SEGMENT
ASSUME CS:CODES,DS:DATAS,SS:STACKS
START:
A1: mov ah,09H ;显示Please input 10 numbers:
mov dx,offset string1
int 21h

INPUT:
mov ah,0AH
MOV DX,OFFSET BUF
INT 21H
FIND:
mov di,00h ;计数负数的个数
mov si,02h

again1:
mov bx,offset BUF
mov aX,[bx+si]
CMP AX,0
JL k

AGAIN2:

cmp si,11h

jmp again1

MOV AH,09H
MOV DX,DI
INT 21H

MOV AH,09H
MOV DX,OFFSET STRING3
INT 21H

P2:
MOV AH,09H
MOV DX,OFFSET STRING4
INT 21H

MOV BL,BUFb+1
MOV BH,0
MOV sI,OFFSET BUFb+2
MOV BYTE PTR[BX+sI],'$'
MOV AH,09H
INT 21H
MOV AH,02H
MOV DL,0AH
INT 21H

k:
mov bp,offset BUFB
MOV byte ptr[bp+SI],AX ????????????????????
inc di
JMP AGAIN2

MOV AH,4CH
INT 21H

END START

画问号的那一行显示error a2070 无效的参数
为什么会错？谢

Answer 1

单独这个问题可以这样修改：
MOV word ptr[bp+SI],AX
AX 是字，不是字节。

Answer 2

大小写。。。。看看对吗？
