1. 通用代码
通用代码类似于一个用汇编语言写程序的一个框架也类似于c语言的头文件编写
assume cs:code,ds:data,ss:stack
data segmentdata endsstack segmentstack endscode segmentstart:mov ax,datamov ds,axmov ax,4c00hint 21hcode ends
end start
2. 数组求和
assume cs:code,ds:data,ss:stack
data segmentarr db 1,2,3,4,10,20,30,40db hello world
data endsstack segmentdb 100 dup (0)
stack endscode segmentstart:mov ax,datamov ds,axmov ax,0mov bx,0mov cx,8for:add al,ds:arr[bx]adc ah,0inc bxloop formov ax,4c00hint 21hcode ends
end startcomment*
vectorintarr{1,2,3,4,10,20,30,40};
int sum 0;
for (int 0;i arr.size();i)sum arr[i];
*comment3. 拷贝数组
assume cs:code,ds:data,ss:stack
data segmentarr db 1,2,3,4,10,20,30,40res db 8 dup (0)
