关于实验5
谁知道第5道和第6道的程序啊？弄了好久总是……
谢谢先~
赞成楼上的。要是实在想不出，给你看看吧，要自己debug哦。第五题assume cs:code
a segment
db 1,2,3,4,5,6,7,8
a ends
b segment
db 1,2,3,4,5,6,7,8
b ends
c segment
db 0,0,0,0,0,0,0,0
c ends
code segment
start: mov ax,a
mov ds,ax
mov ax,b
mov es,ax
mov bx,0
mov cx,8
s: mov al,
add es:,al
inc bx
loop s
mov ax,c
mov ds,ax
mov bx,0
mov cx,8
s0: mov al,es:
mov ,al
inc bx
loop s0
mov ax,4c00h
int 21h
code ends
end start
第六题assume cs:code
a segment
dw 1,2,3,4,5,6,7,8
a ends
b segment
dw 0,0,0,0,0,0,0,0
b ends
code segment
start: mov ax,a
mov ds,ax ;ds指向a段
mov ax,b
mov bx,0 ;ds:bx指向a段的第1个单元
mov ss,ax
mov sp,16 ;设置栈顶指向b:16
mov cx,8
s: push
add bx,2
loop s ;将a段中0～16个单元逆次入栈
code ends
end start
作业自己做，不会就把第6章重新看几遍。按照自己的思路写，多多debug。 assume cs:code
a segment
db 1,2,3,4,5,6,7,8
a ends
b segment
db 1,2,3,4,5,6,7,8
b ends
c1 segment ;注意此处若用 c segment 会报错，c 似乎是个关键字
db 0,0,0,0,0,0,0,0
c1 ends
code segment
start:mov ax,a
mov ds,ax
mov ax,c1
mov es,ax
mov bx,0
mov cx,8
s: mov al,
mov es:,al
inc bx
loop s
mov ax,b
mov ds,ax
mov bx,0
mov cx,8
s0: mov al,
add es:,al
inc bx
loop s0
mov ax,4c00h
int 21h
code ends
end start
