[文本处理] 请大侠帮我完美解决代码

:main
rem  假设功能abc那一列的数据都是不一样的
pause
for /f "delims=, tokens=1,2" %%i in (a.txt) do (
    echo 将要执行%%j
  pause或者ping延时
    findstr /i "%%i" a.txt>>已执行.txt
    findstr /v "%%i" a.txt>>b.txt
    move /y b.txt a.txt
    goto %%i
)

:功能abc
……
goto main

:功能def
……
goto main

类推

（另：假设将 功能abc（类推） 单独建为bat,可以把for里的goto修改为start）

@echo off

set batchmode=0
:main

rem menu
if "%batchmode%"=="1" goto :EOF
echo ===============================
echo 1.功能abc
echo 2.功能def
echo 3.根据a.txt定义批量执行
set /p mode=请选择:

if "%mode%"=="1" goto :功能abc
if "%mode%"=="2" goto :功能def
if "%mode%"=="3" goto :BATCH_MODE

pause
exit 0

:功能abc
echo RUN-功能abc
goto main

:功能def
echo RUN-功能def
goto main

:BATCH_RUN
goto %1
echo 其实不会运行到这里，这行和下一行可以不写
goto :EOF

    echo 将要执行%%j
    call :BATCH_RUN %%i
