不解释了,Debug用法google吧,很多的.

@echo.======== Ver:1.0 ==================== 发布日期: 2012-02-03 ==============
@echo.	BAT_NAME:	HexFile2Ascii.bat
@echo.	返回值:		%def_filename%
@echo.	返回值获得:	┌ set /p strHEX=^<%def_filename%
@echo.			└ echo %%strHEX%%
@echo.	调用:		call HexFile2Ascii.bat HexFileName [outFileName]
@echo.	说明:
@echo.			本批处理是从Ascii2Hex.bat中分离出来的,默认系统XP.
@echo.			转载必须指明出处: "转载自批处理之家 bbs.bathome.net"
@echo.			HexFile必须是 "0E 02 56 FE" 形式,以空格分隔
@echo.			使用第三方工具sed对原始文件预处理,如果没有则跳过该过程.
@echo.	大小限制:	ASCII文件 65279 Byte HEX文件65279*3=195837 Byte
