求助批处理逐字显示字符串的结果为什么带双引号

苦涩的回忆

为什么还字显示有引号
代码如下：
@echo off
title spring-clover
color 0a
mode con: cols=80 lines=22
setlocal enabledelayedexpansion
set "theme=have a relax"
for /l %%a in (1 1 6) do echo.
set /p=                              <nul
call :string "!theme!"
pause
exit
:string
set string=%1
echo !string!
:str
set word=!string:~0,1!
set string=!string:~1!
set /p=!word!<nul&call :sleep 100
if defined string goto str
goto :eof

:sleep
set Time1=%time%
set/a minute1=1%Time1:~3,2%-100
set/a second1=1%Time1:~6,2%%Time1:~-2%0-100000
oop
set Time2=%time%
set/a minute2=1%Time2:~3,2%-100
set/a second2=1%Time2:~6,2%%Time2:~-2%0-100000
set/a difMs=((%minute2%-%minute1%+60)%%60)*60000+%second2%-%second1%
if %difMs% lss %1 goto Loop
goto :eof

1. @echo off & title spring-clover & setlocal enabledelayedexpansion
   
2. set "theme=have.a.relax"
   
3. echo %theme%
   
4. for /l %%i in (0 1 11) do (
   
5.     set /p=!theme:~%%i,1!
   
6.     for /l %%x in (0 1 1000) do ver>nul
   
7. )<nul
   
8. pause>nul

效果是这样为嘛这么长

苦涩的回忆

我那里没有逗号，之所以这么长，我们使用的方法不一样，特别是逐显，我那个可以不限字符数量。
