设AB是⻓度为10的字节数组用串操作指令编写程序实现AB两数组内容的相互交换。 试完善本程序。DATA SEGMENTA DB 1234567890AH ORG 0010HB DB 0AH987654321DATA ENDS LEA SIA LEA DIBMOV CX10 LOPLODSBXCHG ALDI DEC DISTOSB INC DILOOP LOP

完整程序如下：

DATA SEGMENT A DB 1,2,3,4,5,6,7,8,9,0AH B DB 0AH,9,8,7,6,5,4,3,2,1 DATA ENDS

CODE SEGMENT ASSUME CS:CODE, DS:DATA START: MOV AX, DATA MOV DS, AX

LEA SI, A LEA DI, B

MOV CX, 10 LOP: LODSB XCHG AL, [DI] DEC DI STOSB INC DI LOOP LOP

MOV AH, 4CH INT 21H CODE ENDS END START
