设(AX)=1234H (BX)=3456H (CX)=5678H 执行 MOV CH AH MOV CL AL XCH
设(AX)=1234H (BX)=3456H (CX)=5678H 执行 MOV CH AH MOV CL AL XCH
汇编语言 al=13h mov buf[di],al mov ax.dw1[bx][si] mov
写出每条汇编指令执行后,相关寄存器中的值 mov ax,62627 AX= mov ah,31h AX= mov al,
MOV AX,468AH MOV SI,1357H MOV [SI],AX MOV CL,4 SHR BYTE PTR[
若:DS=1000H,BX=1200H,(11350H)=0A5H,(11351H)=3CH.执行指令:MOV 0150
MOV AX,2000H MOW DS,AX MOC CL,4 MOV SI,2000H MOV AL,[SI+1] S
7、MOV AH,7896H ADD AL,AH 上述指令执行后,标志位CF和OF的值是CF=( 1 ),OF=( 0
mov 20H,#0FH CLR C MOV 00H,C 为什么到这里(20H)=00001110B
MOV CX,9 MOV AL,01H MOV SI,1000H NEXT: MOV [SI],AL INC SI SH
程序执行完后,寄存器AH的值为4,寄存器AL的值为74H. 请教计算过程? MOV AH,4 MOV AL,24 MOV
mov al,0fbh ; al=0fbh add al,07h ; al=02h
6.若定义X DW 1001H,执行MOV AH,BYTE PTR X指令后,(AH)=____【16】____.
