用debug察看，结果字符串地址是240h，为什么？ title proc43 page 60,132 .model small .stack 64 .data org 230h ;实际地址是240h 为什么？ buffer db 15,?,15 dup (?) .code main proc far mov ax,@data mov ds,ax

mov cx,0 mov bh,7 mov dx,184fh mov ax,0600h int 10h

mov ah,0ah mov dx,offset buffer int 21h

mov ah,4ch int 21h main endp end main

后来发现改成完整断定义，字符串地址就是ds:230h，这是为什么呢？ title proc43 page 60,132

stseg segment stack db 64 dup(?) stseg ends

dtseg segment org 230h buffer db 15,?,15 dup (?) dtseg ends

cdseg segment main proc far assume ss:stseg,cs:cdseg,ds:dtseg mov ax,dtseg mov ds,ax

mov cx,0 mov bh,7 mov dx,184fh mov ax,0600h int 10h

mov ah,0ah ;mov ah,10 mov dx,offset buffer int 21h

mov ah,4ch int 21h main endp cdseg ends end main
