只要在if语句加上/i，就可以忽略大小写了！本代码大小写字母值相等的！

@echo off
setlocal enabledelayedexpansion
set "zmb= abcdefghijklmnopqrstuvwxyz"
:main
cls
set/p var=请输入字符串：
echo %var%|findstr "^[a-zA-Z]*$">nul||goto main
set/p=字符串之和为：<NUL
:a
if not "!var:~%n%,1!"=="" (
for /l %%a in (1 1 26) do (
if /i "!var:~%n%,1!"=="!zmb:~%%a,1!" (
set/a sum+=%%a 
set/p=!var:~%n%,1!+<NUL
goto :b))
:b
set/a n+=1
goto :a
) else (set/p==!sum!<NUL&echo.)
pause>nul
