MOV AL,BL
MOV CL,4
SHR AL,CL
MOV BH,AL
OR BH,30H
MOV AL,BL
AND AL,OFH
MOV BL,AL
OR BL,30H
INT 3
运行上面程序后,BH=(),BL=()
阅读程序,说明程序执行后BH,BL,AL,CL的值;
MOV BL, 72H
MOV AL, BL
MOV CL, 4
SHR BL, CL
OR BL, 30H
MOV BH, BL
AND AL, OFH
OR AL, 30H
MOV BL, AL
INT 3
BH=(),BL=(),AL=(),CL=()
源程序如下:
MOV AL,0B7H
AND AL,0DDH
XOR AL,81H
OR AL,33H
JP LAB1
