如何从另一个包含空格参数的批处理文件调用批处理文件?

我有两层(以后可能会更多)的批处理文件,这使得我的生活变得更轻松,直到我试图添加路径,其中有空格。

批处理文件1:

@echo off
set thinga=c:\final build
set thingb=\\server\deployment for final buil

echo.
echo thing a: %thinga%
echo thing b: %thingb%
echo.

call lala.bat "%thinga%" "%thingb%"

批处理文件2(lala.bat):

@echo off

echo.
echo. Param 1 %1
echo. Param 2 %2
echo.
set BASE=%1
set TARGET=%2
echo. Want to run:
echo.  doSomethingOnBaseFolder %BASE%
echo.  doSomethingOnBaseSubFolder "%BASE%\bin\release\*" "%TARGET%\"
echo.

其结果是:

doSomethingOnBaseSubFolder ""c:\final build"\bin\release\*" ""\\server\deployment for final buil"\"

但我希望输出

doSomethingOnBaseSubFolder "c:\final build\bin\release\*" "\\server\deployment for final buil\"

没有别的办法逃离这个空间吗?
