第八章 数据处理的两个基本问题
实验七:
assume cs:code,ds:data,es:table
data segment
db '1975','1976','1977','1978','1979','1980','1981','1982','1983'
db '1984','1985','1986','1987','1988','1989','1990','1991','1992'
db '1993','1994','1995'
;以上是表示21年的21个字符串,共占用21*4个字节
dd 16,22,382,1356,2390,8000,16000,24486,50065,97479,140417,197514
dd 345980,590827,803530,1183000,1843000,2759000,3753000,4649000,5937000
;以上是表示21年公司总收的21个dword型数据
dw 3,7,9,13,28,38,130,220,476,778,1001,1442,2258,2793,4037,5635,8226
dw 11542,14430,45257,17800
;以上是表示21年公司雇员人数的21个word型数据
data ends
table segment
db 21 dup('year summ ne ?? ') ;注意这里是定义了21*16个字节
table ends
code segment
start: mov ax,data
mov ds,ax
mov ax,table
mov es,ax
mov bx,0
mov si,0
mov di,0
mov cx,21
s:
mov ax,ds:[di]
mov es:[bx],ax
mov ax,ds:[di][2]
mov es:[bx][2],ax
mov ax,ds:[di+54h]

mov ax,ds:[di+54h][2]
mov es:[bx].5[2],ax
mov ax,ds:[si+0a8h]
mov es:[bx].10,ax
mov dx,[di+54h][2]
mov ax,[di+54h]
div word ptr ds:[si+0a8h]
mov es:[bx].13,ax
add bx,16
add di,4
add si,2
loop s
mov ax,4c00h
int 21h
code ends
end start
