批处理脚本if语句中的用户双引号

似乎有人建议在Windows批处理脚本中使用双引号if if:

IF "%FLAG%"=="1" (do something)

但是,在我的情况下,我发现使用双引号可能会导致脚本在比较时失败。任何人都可以看到这里可能出现的问题吗?

PS:我在脚本中SETLOCAL ENABLEDELAYEDEXPANSION

编辑: 当ECHO%FLAG%为1时,该语句甚至失败。

EDIT2: 这是我的剧本。

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION

set CFG=C:\config
set LOBBYLIST=%CFG%\serverlist_lobby_server.txt
set DBDAEMONLIST=%CFG%\serverlist_daemon_server.txt
set LIST=
set FOLDER=

set /p OP=   Delete 1.Lobby, 2.dbdaemon, All? (1,2,a) 

:BEGIN
if %OP%==1 (GOTO DELETE_LOBBY_DUMP)
if %OP%==2 (GOTO DELETE_DBDAEMON_DUMP)
GOTO END


:DELETE_LOBBY_DUMP
set LIST=%LOBBYLIST%
set FOLDER=LobbyServer
GOTO START_DELETE
:DELETE_DBDAEMON_DUMP
set LIST=%DBDAEMONLIST%
set FOLDER=DBDaemonServer\Lobby
GOTO START_DELETE
:DELETE_ALL
set /a OP = OP + 1
GOTO BEGIN




:START_DELETE
for %%b in (%LIST%) do ( 
    echo %%b
    for /f %%a in (%%b) do ( 
        echo    %%a
        dir \\%%a\c$\Services\%FOLDER%\*.dmp | find "dmp"
        dir \\%%a\c$\WINDOWS\PCHEALTH\ERRORREP\UserDumps\*.hdmp | find "hdmp"
    ))

echo.
echo.

if %isAll%==1 (set isContinue=y
) ELSE (set /p isContinue=   Continue? (y/n)
)

if %isContinue%==y (
    for %%b in (%LIST%) do ( 
        echo %%b
        for /f %%a in (%%b) do ( 
            echo    %%a
            del \\%%a\c$\Services\%FOLDER%\*.dmp
            del \\%%a\c$\WINDOWS\PCHEALTH\ERRORREP\UserDumps\*.hdmp
        )
    )
)

if %isAll%==1 (GOTO DELETE_ALL)

GOTO END
:END

延迟扩展与此无关。

比较失败时%FLAG%的值是多少,即ECHO %FLAG%输出的是什么?
