脚本工作但抛出'命令的语法不正确'。错误

我试图在这里使用这个脚本：http：//www.logaans-site.co.uk/2009/10/17/simpler-version-of-the-7-zip-backup/，它可以工作但是扔了一个“命令的语法不正确。”消息。有人可以告诉我为什么吗？

谢谢

IF /I NOT "%varWaitAtEnd%" == "true" GOTO labelEnd

:labelWaitEnd
PAUSE
:labelEnd

这一行引发了错误：

FOR /F "eol=# tokens=1,2 delims==" %%i IN (%~f1) DO (
SET %%i=%%j
ECHO TRACE: %%i = '%%j'
)
