- 中国大学MOOC: 写出下列程序段执行后,AL、DL的内容分别是( )MOV CL,4MOV AL,87MOV DL,ALAND AL,0FHOR AL,30HSHR DL,CLOR DL,30H
- 执行下列程序段后,写出AX= 【12】 H。 MOV AL,87 MOV CL,4 MOV AH,AL AND AL,OFH OR AL,30H SHR AH,CL OR AH,30H
- 写出下列程序段执行后AX的值为多少? MOV AX, 1234H; AX=(1)H MOV CL, 4 AND AL, 0FH; AX= (2) H ADD AL, 30H; AX= (3)H SHL AH, CL; AX= (4)H AND AH, 0F3H; AX= (5)H
- 设(A)=37H,执行指令ANLA,#0FH后,(A)=_____H A: 07 B: 37 C: 03 D: 30
- 阅读下面程序段: MOV DL,0 MOV CX,8 MOV BL,100AGA: MOV AL,30H SHR BL,1 JNC NEXT MOV AL,31H NEXT: RCL DL,1 MOV AH,0EH INT 10H LOOP AGA执行本程序后DL=_______H;屏幕上显示内容为_______。(注:答案和答案之间用一个空格分开。)
