    this is something seen first time in black bird script,
    after little investigating, it's 2 chars combined together

    ALT 0 1 3 + ALT 0 3 2
    (0D) Carriage Return + (20) Space

    here some working example,
    with color option and this,
    it's a good option to visual your script.
    (it work in console new too)

    Code:
    
@cls
@echo off
cd /d "%~dp0"
setlocal EnableExtensions EnableDelayedExpansion

:: Run as Admin with native shell, any path, params, loop guard, minimal i/o, by AveYo
>nul reg add hkcu\software\classes\.Admin\shell\runas\command /f /ve /d "cmd /x /d /r set \"f0=%%2\" &call \"%%2\" %%3" & set "_= %*"
>nul fltmc || if "%f0%" neq "%~f0" ( cd.>"%tmp%\runas.Admin" & start "%~n0" /high "%tmp%\runas.Admin" "%~f0" "%_:"=""%" &exit /b )

:: make sure before script is running as Admin
:: explorer.exe exist in all version, so we can use it for our benefit
for /f %%a in ('copy %SystemRoot%\explorer.exe nul /z') do set "RET=%%a"

rem Based on BlackBird Idea
rem don't know yet what is this !break! char ?
rem also it work only in !! and not %%
rem interesting behavior

echo:
echo Working ............
echo Working ............
echo Working ............
echo Working ............
echo:

for /l %%i in (0,40,1000) do (
    call :drawProgressBar 000 Process %%i%%%%
    >nul 2>&1 ping 100.0.0.0 -w 1 -n 2
)

echo:
echo:
echo Done^^!
echo:
pause
exit /b

:drawProgressBar
<nul set /p "=%*!RET!"
endlocal
goto :eof

    and a bonus, we can use space in Choice Command.
    we need thus char's (we can use Notepad++ to generate them easily)
    put them like this "!RET! _SPACE_ _SPACE_ _SPACE_ What do you like to do today ?"

    Code:
        :: ALT 0 0 8
    set "BS="
  
    :: ALT 0 0 0 7
    set "BEL="

    (set RET=^
%=Do not remove this line=%
)

    If you want to write in the same line over & over, you can use powershell :
    Code:
    @echo off
for /l %%n in (1,1,20) do (
powershell "write-host '.' -nonewline"
timeout 1 >nul
)
echo;
pause
    for overwriting, insert a carriage return and you can play with colors :
    Code:
    @echo off
for /l %%n in (1,1,20) do (
powershell "write-host \"`r*** test ***\" -nonewline -foregroundcolor red"
timeout 1 >nul
powershell "write-host \"`r*** test ***\" -nonewline -foregroundcolor blue"
timeout 1 >nul
)
echo;
pause
