标题: 难题：对文本中所有数值加1 [打印本页]
作者: bat-zw 时间: 2008-4-18 20:28 标题: 难题：对文本中所有数值加1
a.txt内容如下：
36d5c496a5863f4f4572d1z69
456-d_fhs234f123hi7459213
gh53176ffsfj_74824535-fj4
要求通过批处理生成b.txt内容如下，即对a.txt中所有数值加1（满10归0），但其它的不变：456-d_fhs234f123hi7459213
gh53176ffsfj_74824535-fj4
47d6c507a6974f5f5683d2z70
567-d_fhs345f234hi8560324
gh64287ffsfj_85935646-fj5
注：并不知道任一字符串的长度567-d_fhs345f234hi8560324
gh64287ffsfj_85935646-fj5

高！竟然有这招，判断str的值是否为空
请教一下 最后set str2=是什么意思？ 如果去掉 会显示

set str=就是清空变量str以便下一次的追加赋值。
