题目更改后很简单。
A1：
@echo off
set str=I love,bbs;bathome=net
for %%I in (%str%) do  echo "%%I"
pause

A2：
@echo off
set str=I love,bbs;bathome=net
for %%i in (%str%) do if %%i==net echo %%i
pause



最初的题目（条件str=I love,bbs;bathhome.net），难度高。

   你设置了STR变量就可以直接引用了啊

@echo off
echo 分隔符1：逗号
for %%i in (I,LOVE,BBS,BATHOME,NET) do echo %%i
echo ____________________________________________
echo 分隔符2：分号
for %%i in (I;LOVE;BBS;BATHOME;NET) do echo %%i

@echo off

pauseCOPY

A2:

@echo off
set str=I love,bbs;bathome=net
for %%i in (%str%) do if exist %%i echo %%i

A2乱试出来的，有点想加个不存在的出错代码提示，结果发现可以得到最后一个匹配值...

用for语句建立test1.txt、test2.txt和test3.txt三个文本文件。
@echo off
for %%a in (text1 text2 text3) do md %%a
pause

A1：假设令 set str=I love,bbs;bathome=net，请分别显示出I、love、bbs、bathome和net这五个字符串。目的：了解for语句用到了哪些符号作为元素的分隔符。

@echo off
set str="I love,bbs;bathome=net"
for /f "tokens=1,2,3,4,5 delims=,;= " %%i in ( %str% ) do ( 
echo %%i
echo %%j
echo %%k
echo %%l
echo %%m
)
pause>nulCOPY

A2：条件同A1，要求最后只显示net这个字符串。目的：了解for语句的执行流程。

@echo off
set str="I love,bbs;bathome=net"
for /f "tokens=5 delims=,;= " %%i in ( %str% ) do echo %%i
pause>nulCOPY

@echo off
echo.新手试题上路中^^_^^……
set str=I love,bbs;bathome=net
for /f "tokens=1-5 delims=;=, " %%i in ("%str%") do echo %%i %%j %%k %%l %%m
:: 发现delims=;=,  里边的空格必须放在最后，且放在 TOKENS后，如果没有空格可以随便写
pause>nul
for /f "delims== tokens=2" %%i in ("%str%") do echo %%i
pause>nul

练习A1：
@echo off
set str=I love,bbs;bathome=net
for %%i in (%str%) do echo %%i
pause

练习A2：
@echo off
set str=I love,bbs;bathome=net
for %%i in (%str%) do set str2=%%i
echo %str2%
pause

第一题：
照葫芦画瓢
@echo off
set str=I love,bbs;bathome=net
for %%i in (%str%) do echo "%%i"
pause

第二题还没学会

n度自由

set str=I love,bbs;bathome=net && @for /f "tokens=1-5 delims=,;=" %i in ("%str%") do @echo %i %j %k %l
