批处理for语句从入门到精通配套练习题

woshi110

检查下我这个吧：
rem  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。
set str=I love,bbs;bathome=net
for %%i in (%str%) do  
pause&&exit


rem 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
set str=I love,bbs;bathome=net
for %%i in (%str%) do (
        echo %%i>kbc.txt
        findstr "net" kbc.txt
)
pause&&exit
