 | 一个基础的汇编例题，要求用汇编语言实现R<-X+Y-3
其中R·X·Y都是字数组，要求X,Y放在D_SEG段，R放在E_SEG段
D_SEG segment
x dw 200,241,308,102,1247
y dw 20,25,2530,888,356
D_SEG ends
E_SEG segment
r dw 5 dup(?)
E_SEG ends
datagroup group D_SEG,E_SEG
code segment
assume cs:code,ds:datagroup
main proc far
mov ax,datagroup
mov ds,ax
call compute
mov ax,4c00h
int 21h
main endp
compute proc near
mov cx,5
mov si,0
next:
mov ax,x[si]
add ax,y[si]
sub ax,3
mov r[si],ax
add si,2
loop next
mov cx,5
add di,0
net:
mov bx,r[di]
push cx
call put
call crlf
add di,2
pop cx
loop net
ret
compute endp
put proc near
mov cx,10000d
call output
mov cx,1000d
call output
mov cx,100d
call output
mov cx,10d
call output
mov cx,1d
call output
ret
put endp
output proc near
mov ax,bx
mov dx,0
div cx
mov bx,dx
mov dl,al
add dl,30h
mov ah,2
int 21h
ret
output endp
crlf proc near
mov dl,0ah
mov ah,2
int 21h
mov dl,0dh
mov ah,2
int 21h
ret
crlf endp
code ends
end main
