为解决一个网友的问题刚写的，16进制字符文本/二进制文件迷你互转器
(由于带有回车换行选择性处理的开关，加上0D 0A可以是要处理的二进制数据，也可以是回车换行，所以虽说是小意思，但写的过程中还是颇费一些心思的。。)
对学习字符，数值处理很有帮助的。。。
加了，简单的输入检测和帮助
更新了。
VW2su1QR.rarreadme.txt
***********************
编译工具：TC3 VC6
语法：
txt2bin 文本文件名 二进制文件名 [/killline|n]
/killline 去除回车换行
n 以每隔n对16进制字符添加一个回车换行
例子：
txt2bin file.txt file.bin
txt2bin file.txt file.bin /killline
txt2bin file.txt file.bin 10
bin2txt 二进制文件名 文本文件名 [/killline|n] [/lower]
/killline 去除回车换行
n 以每隔n个字节添加一个回车换行
/lower 以小写方式
例子：
bin2txt file.bin file.txt
bin2txt file.bin file.txt /killline
bin2txt file.bin file.txt 10
bin2txt file.bin file.txt 10 /lower
