（QQ:13916830 哈工大紫丁香BBSID:iamxiaohan）
前言
这两天翻看一本C 语言书的时候，发现上面有一段这样写到
例：将同一实型数分别赋值给单精度实型和双精度实型，然后打印输出。
#include <stdio.h>
main()
{
float a
double b
a = 123456.789e4
b = 123456.789e4
printf(“％f\\n％f\\n”,a,b)
}
运行结果如下：-analysis framework and the C language CPU float mechanism Version 0.0 a Harbin Industrial University Shushan wave (email : xieyubo@126.com website : http://purec.binghua.com) (QQ : HIT lilac BBSID 13916830 : iamxiaohan) Introduction The two epoch-making book on the C language, discovered that there are some cases written : the same number of each type is assigned to the single-precision and double-real float, then print output. # Include

Description: 移植到MCS51的uCOS_II。
1。在文件OS_CORE.C中OSMapTbl和OSUnMapTbl数组用于查表，所以应该放在code里。
增加code关键字。UCOS_II.H和OS_CORE.C。
2。OS_CFG.H堆栈大小MaxStkSize改为900。
3。OS_CPU_C.C的InitTimer0函数增加了关于开T0中断的解释。
允许T0中断，此时EA=0(51上电缺省值)，中断还不会发生，满足在OSStart()前不产生中断的要求。
4。修改中断处理流程，以便严密监视中断嵌套情况。每个中断进入后立即进行OSIntNesting+1原语操作。
5。增加printf函数的移植，支持灵活的数据显示。支持标准或长二进制/八进制/十进制/十六进制/无符号整数，
支持字符、字符串、浮点数、百分号％。其中，浮点数在整个范围内被完全支持，统一采用科学记数法显示。
-transplanted to the MCS51 uCOS_II. 1. In the document which OSMapTbl OS_CORE.C and OSUnMapTbl array for Lookup, Therefore, it should be placed on code Lane. Increased code keyword.

Allow T0 interruption, this time EA = 0 (51 electricity default value), also will not be interrupted. meet the OSStart () do not have interrupted the former requirements. 4.

现传上源码...希望能对正学习DOS,WINDOWS,磁盘和编程者有点帮助...
内含纯DOS,WIN32控制台和WIN32 GUI三个版本.它们生成的备份文件可以在任何版本中使用.
WIN32 GUI版本暂使用备份功能(其他模块也都已全部写好,全是完整的,现在仅开启备份功能),如果想使用还原替换和比较功能,可自行打开调用的开关或加几句调用的代码就可以了, 一会儿我再把它们加上去,...
(在WIN,打印功能是不能使用直接使用DOS的代码的,要把它们先送到编辑框的缓冲区再显示的...有兴趣的也可自己弄...)
因刚刚从DOS代码转写成WIN,程序提示还没有完全改写成WIN的,printf()等还留在里面,不过对编译没有影响,有时间可以改写掉,
因时间关系,没有详细的注释,不过在写的时候,变量名字基本是根据其功能起的,所以,对程序的代码思路还是不难理解的-Backup partition table for miniTO source is on the traditional source of hope ... is learning DOS, Windows, disk and programmers a little help ... containing pure DOS.

Description: （1） 给定一段符合Pascal子集语法的语言，能成功转换成C语言；
（2） 一个简单的说明文档；
（3） 2007.7.14之前上传到ftp:// C07:C07@10.11.3.71/upload,用学号建立自己的目录；
（4） （可额外加分5分）若有出错处理功能，请在说明文档中写明可以处理哪几项错误。
注意事项：
（1） 两人一组
（2） 可以使用词法、语法自动生成工具，windows下有Flex，Bison，Linux下有Lex，Yacc，Java的有Jlex，JavaCC，ANTLR等
（3） 不用考虑Pascal和C的关键词不同问题，即Pascal子集语言中假设不出现int，for等作为变量标志符
（4） read()和write()可用由scanf()，printf()等组成的语句转换。
（5） 如果有疑问可以发信给我 xpqiu@fudan.edu.cn.
