最近看到一批处理,请问其中的变量 b 是什么意识?起什么作用???
百思不得其解???
@echo off
setlocal enabledelayedexpansion&cls&color 0f&title Welcome to CN-DOS!
set "a= CN-DOS"
set "b="
set "c=12345689abcde"
echo\
:c
for /l %%a in (6,1,28) do (
set /a d=%random%%%13+1
call :pp %%a
)
goto c
:pp
set/p=!a:~-%1!<nul
set/p=!b:~0,%1!<nul
color 0!c:~%d%,1!
goto :eof
