goto:eof 这个呢？跟exit /b 有区别吗？我有个代码，加了goto:eof 用来结束调用，他直接死循环了，代码如下：
@echo off
GOTO START
:start_system
%1 %2
ver|find "5.">nul&&goto :Admin
mshta vbscript:createobject("shell.application").shellexecute("%~s0","goto :Admin","","runas",1)(window.close)&goto :eof
:Admin
set path=%~dp0
echo install mysql service...
echo %path%
cd %path%\bin\
mysqld.exe --remove mysql
mysqld.exe --install mysql
echo start mysql Serviceo
"%SystemRoot%"\system32\net start mysql
GOTO:eof
:start
CALL:start_system
pause
