Hi, Sorry again for the ignorance. I have a NSString str with "ABCDEFGHI" on it. I am for many hours trying to find a way to retrive from letter i n letters and have it in another NSString. Like NSString str2 = [str GETPARTOFSTRINGFROM:2 LENGHT:3] would return "CDE" Anyone has a simple routine to do that? Is there a function that would do that? Thanks again for the help.
