[文本处理] 求助批处理for循环里如何顺序输出字母？

dong3626

如题，，在for循环里，根据变量输出指定字符
比如，a c e ...

@echo off
setlocal enabledelayedexpansion

for /l %%a in (1, 2, 26) do (
   echo ABCDEFGHIJKLMNOPQRSTUVWXYZ:~%%a,1
)


pause>nul
复制代码

terse

@echo off
setlocal enabledelayedexpansion
set "str=ABCDEFGHIJKLMNOPQRSTUVWXYZ"
for /l %%a in (0, 2, 25) do (
   echo !str:~%%a,1!
)
pause>nul
复制代码
