最近要把一个其他系统上的程序移植到Windows，其中用到一个数据文件，用原来的程序在Windows上编译后，一运行就访问越界，跟踪后发现，解析文件数据时，凡是读取ULong的地方，数据都取反了，问了一下，原来系统是基于Motorola的CPU的，而motorola CPU同Intel CPU的Word中高低位字节存放顺序正好是反的，因此ULong转换失败，写了一个高低字节转换程序就OK了。这应该是异构系统移植一个常见问题

 下面的规则是非贪婪模式的语法，它会匹配{之后的任意字符而不会匹配}符号，

CURLY_BLOCK_SCARF
    :   '{' (.)* '}'
    ;
 
要想让Antlr能够匹配}，我们需要将规则改为
 

.-noscript-blocked { border: 1px solid red !important; background: white url("chrome://noscript/skin/icon32.png") no-repeat left top !important; opacity: 0.6 !important; }

新建一个Win32 DLL项目，设置如下

在VC中可以Export DLL函数供C程序调用

#define PARSERDLL_API __declspec(dllexport)

extern "C" {
PARSERDLL_API int GetSqlType(LPCTSTR szSql);
}

Delphi要想调用这样的针对C输出的函数，不能使用stdcall的调用规范，而应使用cdecl的调用规范

在Antlr生成cpp文件时，我们可能希望添加预编译头文件StdAfx.h到cpp文件中，标准的Header开关只能把头文件include到生成的头文件，而不能是cpp文件。

要想添加头文件到cpp中，需要使用antlr cpp生成器特殊控制开关关键字pre_include_cpp，示意如下
header "pre_include_cpp" {
#include "StdAfx.h"
}

.-noscript-blocked { border: 1px solid red !important; background: white url("chrome://noscript/skin/icon32.png") no-repeat left top !important; opacity: 0.6 !important; }

column_ref_2[string& szTableName, string& szColumnName]
{
string s1,s2,s3, s4="";
}
:

c:id { s1=#c->getText();}
(PERIOD c1:id { s2=#c1->getText();}
(PERIOD c2:id { s3=#c2->getText();}
(PERIOD c3:id { s4=#c3->getText();}
)?)?)?
{
if (s2=="")
{
