[文本处理] 请教为何批处理设置的变量使用IF框起来后就不正确了？

@echo off
set egg=6
set C_PATH=c:\KL500\C
set D_PATH=d:\kl300\D
echo cpath=%C_PATH%
echo dpath=%D_PATH%
if "%egg%"=="6" CALL :DZPATH "%C_PATH%" "%D_PATH%"
echo =====================================
set aaa=%dzdk1%
echo aaa=%aaa%
set bbb=%dzdk2%
echo bbb=%bbb%
set CEP=%dzdk1%%dzp1%
set DGP=%dzdk2%%dzp2%
echo CEP=%CEP%
echo DGP=%DGP%
echo =====================================
pause

:END
goto:eof
