substr()
But might I suggest that if you can get into a Perl way of thinking that
you probably won't want to access the individual characters. I know it
can be difficult if you are coming from C for example, but in Perl there
are usually better ways of doing whatever you are doing. (Of course, I
have no idea what you are doing.) The better ways usually involve
regular expressions.

Fine, but please consider the sanity of whoever will be maintaining this
code and stick to the first suggestion. You never know, it might even
be you.
