将纯数字字符串拆分为单个数字

1. s='1234abcd'
   
2. -- 拆分成{"1","2","3","4","a","b","c","d"}
   
3. k=strlen(s)
   
4. list1={}
   
5. for i=1,k do
   
6.     list1[i]=strsub(s,i,i)
   
7. end
   
8. for i=1,k do
   
9.     print(list1[i])
   
10. end
    
11. 
    
12. 注：lua4脚本
    
13. 若是lua5，strlen改为string.len，strsub改为string.sub
