批處理特效之“看我倒背如流”最后由 batman 于 -8-17 00:02&&相信大家都知道倒背如流的意思吧，下面我們就用批來模擬對文本的倒背特效：

@echo off&setlocal enabledelayedexpansion
rem 因論壇處理不了制表符，請將下面tab=后面的空格替換為制表符再運行代碼
set tab=
for /l %%a in (10000,1,11000) do (
set tg=!tg!&set k=!k! 
set str=%%a&set code=!str:~1!!code!
)
echo,&echo,┌────────────────────┐
echo,&echo,└────────────────────┘
echo,%tab%%tg:~,24%
for /l %%a in (1,1,20) do (
set /a bf=%%a*5,n=40-2*%%a
set /p=!tg!│<nul
for /l %%b in (1,1,%%a) do set /p=■<nul
for %%i in (!n!) do set /p=!k:~,%%i!│文本閱讀中，請稍等...!bf!%%<nul
for /l %%c in (1,1,2000) do echo,>nul
)
cls&&echo,&echo,下面且看我倒背如流：&echo,
for /f tokens=1* delims=: %%a in ('findstr /n .* a.txt') do (
set _%%a=%%b&set /a n=%%a&echo,
)
for /l %%a in (%n%,-1,1) do (
set /a s=n-%%a+1,m=s*10+12
for /l %%b in (1,1,!s!) do echo,
for %%b in (!m!) do echo,%tab%!tg:~,%%b!
if defined _%%a (
set str=!_%%a!!_%%a!!_%%a!!_%%a!%code%
set /a sw=1!str:~4000,4! %% 10000
for /l %%b in (1,1,!sw!) do (
set /a kw=sw-%%b
for %%c in (!kw!) do set /p=!k:~,%%c!!_%%a:~-%%b,%%b!<nul
for /l %%c in (1,1,200) do echo,>nul
set /p=!tg!<nul
)
)
)
pause>nul

暫只適用于每行少于80個字符的純英文文本，測試文本a.txt如下：

I loved you, and I probably still do,
 
And for a while the feeling may remain... 
But let my love no longer trouble you, 
I do not wish to cause you any pain. 
I loved you; and the hopelessness I knew, 
The jealousy, the shyness - though in vain - 
Made up a love so tender and so true
