比如说我想在AA下的1.exe运行一段时间后运行另外一个程序如BB下的2.exe我该怎么写！
@echo off
cls
@echo off
:top
call w.bat box @dos.bat:menu
if "%?%"=="1" goto AA
if "%?%"=="2" goto BB
if "%?%"=="3" goto CC
if "%?%"=="4" goto DD
if "%?%"=="5" goto EE
if "%?%"=="6" goto FF
if "%?%"=="7" goto exit
goto exit
:menu
======= Select an item to run =======
[1.AA ]
[2.BB ]
[3.CC ]
[4.DD ]
[5.EE ]
[6.FF ]
[7.EXIT ]
Use dos.bat to show this menu in dos
::

:AA
1.EXE
goto exit

:BB
2.exe
goto exit

:CC
3.exe
goto exit

:DD
4.bat
goto exit

:EE
5.exe
goto exit

:FF
6.exe
goto exit

:exit

什么叫运行一段时间后？

@echo off
cls
:: 设置依次菜单调用之间的延时，假设为10秒
set timeout=10

:: 设置用 mpos 环境变量保存程序调用上一个菜单处的位置
set mpos=

@echo off
:top
call w.bat box @dos.bat:menu #%mpos%+1,%timeout%
if "%?%"=="1" goto AA
if "%?%"=="2" goto BB
if "%?%"=="3" goto CC
if "%?%"=="4" goto DD
if "%?%"=="5" goto EE
if "%?%"=="6" goto FF
if "%?%"=="7" goto exit
goto exit
:menu
======= Select an item to run =======
[1.AA ]
[2.BB ]
[3.CC ]
[4.DD ]
[5.EE ]
[6.FF ]
[7.EXIT ]
Use dos.bat to show this menu in dos
::

:AA
1.EXE
goto top

:BB
2.exe
goto top

:CC
3.exe
goto top

:DD
4.bat
goto top

:EE
5.exe
goto top

:FF
6.exe
goto top

:exit
:: 清空环境变量
set ?=
for %%a in (wbat timeout mpos) do set %%a=

多任务?
