Is there a way I can pass an array or a hash across the socket without formatting it to ASCII first then having to reassemble on the other end?
Not that I'm aware of. Passing any sort of data over a socket requires a serialization process.

If you are looking for modules which will do a lot of the work for you, have a look at Storable - it will serialize just about anything.

Update: Also have a look at IPC::Socket::SIPC.

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.
  • Please read these before you post! —

  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
