C/C++ 汇编

可以采用10号功能调用输入字符串，用 9号功能调用输出提示信息。先比较长度是否相等。源代码如下

.386
DATA SEGMENT USE16
    BUF1 DB 80,?,80 DUP(0)
    BUF2 DB 80,?,80 DUP(0)
    M DB 0AH,0DH,'MATCH !$'
    NM DB 0AH,0DH,'NO MATCH !$'
DATA ENDS
CODE SEGMENT USE16
    ASSUME DS:DATA,CS:CODE
START:  MOV AX,DATA
        MOV DS,AX
        LEA DX,BUF1
        MOV AH,10
        INT 21H
        
        MOV DL,0AH
        MOV AH,2
        INT 21H
        MOV DL,0DH
        MOV AH,2
        INT 21H
        
        LEA DX,BUF2
        MOV AH,10
        INT 21H
        
        MOV AL,BUF1+1
        MOV AH,BUF2+1
        CMP AH,AL
        JNE NO
        MOV AH,00H
        MOV DI,0
s:      MOV BL,BUF1+2[DI]
        MOV BH,BUF2+2[DI]
        CMP BH,BL
        JNE NO
        INC DI
        CMP DI,AX
        JB S
        MOV AL,0
        LEA DX,M
        MOV AH,9
        INT 21H
        MOV AH,4CH
        INT 21H
NO:     LEA DX,NM
        MOV AH,9
        INT 21H
        MOV AH,4CH
        INT 21H
CODE ENDS
    END START
