程序： 书上的例程（文件名P10.asm）
.386
.model flat,stdcall
option casemap:none
include \masm32\include\windows.inc
include \masm32\include\kerne132.inc
include \masm32\include\user32.inc
includelib \masm32\lib\user32.lib
includelib \masm32\lib\kernel32.lib

.date
MsgCaption    db "hi,masm32!",0
MsgBoxText    db "win32 assembly is great!",0

.code
start:
invoke MessageBox,NULL,addr MsgBoxText, addr MsgCaption,MB_ok
invoke Exitprocess,NULL
end start

我用MASM32 V10编译如图

还有书上说了个设置环境变量的批处理文件
我MASM32安装在C盘  
@echo off
set include=c:\masm32\include
set lib=c:\masm32\lib;c:\masm32\m32lib;d:\program files\microsoft sd\lib
setpath=c:\masm32\lib;c:\masm32\m32lib;d:\program files\microsoft sd\bin
start cmd.exe /k
@echo on
怎么就没有用呢，把这个BAT放入C盘运行提示信息

因为上面提示的是 不能打开那个文件 所以换了个程序
; p227.asm
;
.model flat,c
      PUBLIC power2
_TEXT SEGMENT WORD PUBLIC 'CODE'
_power2 PROC
   
     push ebp
     mov ebp,esp
     mov eax,[ebp+4]
     mov ecx,[ebp+6]
     mov eax,cl
     pop ebp
     ret
 
_power2 ENDP
_TEXT ENDS
      END

执行结果：

回一楼，你可以直接在我的电脑右键属性，高级。环境变量。里添加。lib path include 分别把路径打上。
若是本来有lib的那么在后面加的话要这样   ;c:\masm32\lib
其它一样。path ==>c:\masm32\path
就这样就OK了。
若是设了这个的话。
include \masm32\include\windows.inc
改为includ windows.inc
