预备知识：

　　清屏：若要显示这些数据，不希望被之前的信息所影响，所以先把屏幕清理；

assume cs:codestack segmentdw 16 dup(0)code segmentstart:mov ax,stackmov ss,axmov sp,16mov ax,0b800hmov es,axpush bp     ;保留现场，虽然没什么用，但是要养成习惯push cxmov bp,0    ;行mov cx,22   ;一共有22行需要清屏s1:mov si,0push cxmov cx,80   ;每一行有80个字符s2:mov byte ptr es:[bp+si],0   ;空字符mov byte ptr es:[bp+si+1],7 ;属性add si,2loop s2add bp,160pop cxloop s1pop cxpop bpmov ax,4c00h                ;不要忘了正常退出int 21h
code ends
end start

写成函数的形式：

assume cs:codestack segmentdw 16 dup(0)code segment
start:main:mov ax,stackmov ss,axmov sp,16mov ax,0b800hmov es,axcall sub1mov ax,4c00h                ;不要忘了正常退出int 21hsub1:push bp     ;保留现场，虽然没什么用，但是要养成习惯push cxmov bp,0    ;行mov cx,22   ;一共有22行需要清屏s1:mov si,0push cxmov cx,80   ;每一行有80个字符s2:mov byte ptr es:[bp+si],0   ;空字符mov byte ptr es:[bp+si+1],7 ;属性add si,2loop s2add bp,160pop cxloop s1pop cxpop bpretcode ends
end start

效果相同

对于字符串的显示程序：

assume cs:codestack segmentdw 16 dup (0)
stack endsdata segmentdb '1975','1976','1977','1978','1979','1980','1981','1982','1983'db '1984','1985','1986','1987','1988','1989','1990','1991','1992'db '1993','1994','1995'
data endscode segment
start:main:mov ax,stackmov ss,axmov sp,16mov ax,datamov ds,axmov ax,0b800h   ;显示段mov es,axmov bx,0mov bp,160      ;行add bp,160mov cx,21s1:mov si,0        ;列push cxmov cx,4s2:call show_yearadd si,2inc bxloop s2add bp,160pop cxloop s1mov ax,4c00hint 21hshow_year:push axmov al,[bx]mov es:[bp+si],almov byte ptr es:[bp+si+1],02h   ;注意这里要用byte ptrpop axret
code ends
end start

　　

 

要求：把试验七的数据显示在屏幕上
