我从互联网上尝试了一些github代码,但是当我在EXE Templete中编写相同的代码时,它不起作用。
data segment
selection db ?
;FILE I/O DATAS
dir1 db "c:\test1", 0
dir2 db "test2", 0
dir3 db "newname", 0
file1 db "c:\test1\file1.txt", 0
file2 db "c:\test1\newfile.txt", 0
file3 db "t1.txt", 0
handle dw ?
text db "lazy dog jumps over red fox."
text_size = $ - offset text
text2 db "hi!"
text2_size = $ - offset text2
ends

仿真器说:“目录已存在: D:\ Programlar \ emu8086 \ MyBuild \“
但是我没有声明该目录位于MyBuild中,它应该位于vdrive / C中
答案 0 :(得分:0)
您必须在这些代码行中使用COM文件模板。
.model small
.stack 64
.data
.code
mov ax,@data
mov ds,ax
