		echo !servernum!
		copy %vdisk%\run\1.txt \\!servernum!\work\nook.txt >nul
		echo ERRORLEVEL=!errorlevel!
		if !errorlevel! equ 0 (copy %vdisk%\run\1.txt \\!servernum!\work\!kkk:~0,-4!.txt >nul) else (set !winservernum!=false&&echo %date%%time%服务器：!servernum!无法连接，放弃对此机发送指令！)
		del /q %wdisk%\server\ready\!kkk:~0,-4!.txt 2>nul
		timeout -t 10
		goto fenpei
		)
	)
)
)
for /l %%a in (%serverst%,1,%serverend%) do (
echo !win%%a!
)
pause

这段代码的问题我自己觉得莫名其妙
首先，set !servernum!=false。但是echo !servernum!仍然是win101
其次，copy %vdisk%\run\1.txt \\!servernum!\work\nook.txt >nul肯定不能成功，但!errorlevel!值却是0
麻烦哪位大神能解释下原因。拜谢拜谢

set !servernum!=false ×
set servernum=false   √

那么如何在这个情况下给变量名称赋值

bbaa

你赋值给的变量名是!servername!里的值
