看下面的小程序,很简单,你认为执行结果会是什么? ------------------------------------------------------------ ;文件名:11.ASM ;利用console显示一个字符串信息
.386 .model flat,stdcall option casemap:none
include /MASM7/INCLUDE/windows.inc include /MASM7/INCLUDE/kernel32.inc include /MASM7/INCLUDE/masm32.inc
includelib /MASM7/LIB/kernel32.lib includelib /MASM7/LIB/masm32.lib
.code messAdd dd 0 mess db 'How are you !',0
start: lea eax,mess mov messAdd,eax ;写代码段中的数据 invoke StdOut,messAdd invoke ExitProcess,NULL end start -----------------------------------------------------------
太简单啦,不就是利用console输出一个字符串?对啦,这就是程序的原意! 但结果却不是想象的。因为在执行程序时,映入我们眼帘的首先是一个错误的消息框! 为什么会这样呢?因为Windows在链接时设置代码段一个属性,那就是“读/执行/代码”,就是不允许写。所以就出错啦!有没有解决的办法呢?
照着下面的操作吧,它可使代码段有写的属性:
