call :test
ECHO After "call", this wil be executed.
:test
echo Just a test
REM 难道一定要把 :test 放在最后或者使用 Goto语句才能不执行下边语句
echo I don't want this to be executed inside "test", it should be executed after "call".
ECHO After "call", this wil be executed.

echo I don't want this to be executed inside "test", it should be executed after "call".

call :test

goto :eof
:test
echo Just a test
goto :eof
echo I don't want this to be executed inside "test", it should be executed after "call".

1 :: echo I don't want this to be executed inside "test", it should be executed after "call".
2 rem echo I don't want this to be executed inside "test", it should be executed after "call".
3 设立个条件，加在前面：
set /a n+=1&call :test
ECHO After "call", this wil be executed.
goto :eof
:test
echo Just a test
if %n% lss 2 goto :eof
echo I don't want this to be executed inside "test", it should be executed after "call".
以上代码当call :test被执行一次以上后，每次将执行后面的echo I don't want this to be executed inside "test", it should be executed，第一次时不会执行。ECHO After "call", this wil be executed.
goto :eof
:test
echo Just a test
if %n% lss 2 goto :eof
echo I don't want this to be executed inside "test", it should be executed after "call".

谢谢各位, 这证实了"Call" 调用标签的局限性.
不像高级语言中可以用 END Procedure 之类来表示一个子程序的结束.
看来只能用GOTO 来解决, 或者放在最后.
三楼技巧虽好, 但似乎脱离了本贴的主题. 有点杀鸡用牛刀的感觉. 不过说实话, 我编不出类似三楼的代码, 如果我从来没看过这样的代码.

没意思
call 有它的作用，goto也有它的作用
