you could use unpack instead of hex; pack is definitly wrong.
remember: hex is a string (representation) of an (integer) value.
pack creates a (one) string out of (multiple) values.
unpack creates (multiple) values out of a (one) string.

Therefore it is better to wrap the var in () in a call to unpack.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • 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.
