Question

快帮我看看这段汇编代码错在哪里

这是我抄书的代码：
TITLE ADD and Subtract (AddSub.asm)
; This program adds and subtracts 32-bit integers

.386
.model flat,stdcall
.stack 4096
ExitProcess PROTO,dwExitCode:DWORD
DumpRegs PROTO

.code
main PROC

mov eax,10000h ;EAX=10000h
add eax,40000h ;EAX=50000h
sub eax,20000h ;EAX=30000h
call DumpRegs ;display registers

INVOKE ExitProcess,0
main ENDP
END main
这是Mast for windows 提示的错误信息：
tempfile.obj: error LNK2001: unresolved external symbol _ExitProcess@4
本人小白，刚刚学汇编，没看懂，望大神请教

Answer 1

invoke ExitProcess,0
这个是个API函数，你必须包含相应的头！
include windows.inc
include kernel32.inc
includelib kernel32.lib
自己设置下环境变量

Answer 2

在文件头加上
.386
.model flat,stdcall
option casemap:none
include windows.inc
include kernel32.inc
includelib kernel32.lib
