People are giving you lots of little recipes, without explaining how they work. The basic idea is this:
In Perl, you can just use a number in a scalar as a string.
Perl will convert it for you, from number to string, if necessary. So, all you have to do is extract the first character from the number treated as a string. That's what substr, unpack, the regex /^(.)/ all do.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
