Simulate a funny boot screen with batch processing - China DOS Union Forum

There is also the forum moderator. Why does the following code only display b%% instead of 123? Can variables not be nested?
CODE:
--------------------------------------------------------------------------------

set a=123456789
set b=3
echo %a:~0,%b%%

This is why you need to use setlocal ENABLEDELAYEDEXPANSION to enable delayed environment variables. Of course, it doesn't mean that you can't achieve variable nesting without enabling delayed environment variables. For example, you can convert it by superimposing display commands:

echo %a:~0,^%b%^% | findstr .

The delay uses the code of brother 3742668, but I think the effect is not very good
@echo off
setlocal enabledelayedexpansion
set /a b=81
set a=">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>================================================================================"

:back
cls
for /l %%i in (1,1,20) do @echo.
echo Loading Windows 2000...
set /a b-=1
echo !a:~%b%,80!
if !b! == 1 goto :eof
call :delay 80
goto back

:delay
set /a num=num + 1
if %num% geq %1 (set num=) && goto :eof
goto delay

Another
1.jpg is the result with @echo off!

2.jpg is the result without @echo off!

Originally, it's a winxp sp1 system! :o

Now testing under the SP2 environment, the situation remains the same!

Based on the discussions of the诸位 above, I'll give a summary speech. The batch processing is as follows:


@echo off
setlocal EnableDelayedExpansion

set _tmp_F_S=C:\_delay.vbs
set _tmp_F_F=C:\_tmp.tmp
set delay=50
set s1=Booting
set s2=Booting fast
set s3=Damn it, booting
set s4=Are you going to boot or not, you bastard
set s5=Damn it!! If you don't boot again, I'll smash you!!
echo if WScript.Arguments.count = 1 then WScript.Sleep CInt(WScript.Arguments(0)) end if>%_tmp_F_S%

I don't understand what the person above means. Is it saying the screen flickering at the end?

```batch
@echo off
color 1f
title.
mode con lines=10
rem Progress bar ▉▉▉▉▉
set work=0
set n=0
set mo=0
set number=0
rem all is the total number
set all=60
set time=%all%
:show

:check
if %number% GTR %mo% set num=%num%▉&set /a mo=%mo%+1&goto check

:2

cls
echo Progress: %n% / %all% Remaining time: %time% seconds
echo.
echo.
echo Completed %work% %%%
echo.
if not "%num%"=="" echo %num%
if not "%num%"=="" echo %num%

if %work%==100 goto end

ping 127.1 -n 3 >nul
set /a n=%n%+1
set /a time=%all%-%n%
set /a work=(%n%)*100/(%all%)
set /a number=%work%/3
set /a number=%number%+1
goto show
endlocal

:end
endlocal
pause>nul
```

It's very interesting. I tried it and it really works.
