Your `$array[0]` is not an array but a (scalar) string. see How can I access or change N characters of a string?. Me, too, wanted to point you to perlintro, but perhaps you should have a glance at perldsc and - more importantly - on How do I post a question effectively?	[reply] [d/l]

There is no '4' element in `$array[0]` for you to access. `$array[0]` is the string "4601". It is not an array (or an array reference), exactly like the error message you quoted says: Can't use string ("4601") as an ARRAY ref Because it is not an array, it has no elements for you to access. Perhaps you're coming from C and assuming that strings are arrays of characters? If so, then you need to understand that they aren't. In Perl, a string is a basic data type. A single value. Not an array of characters.	[reply] [d/l] [select]
