Dump the "&" in front of subroutine calls.
  1. Using & disables a function's prototype.
  2. If you don't pass any parameters to a function, but call it using &, it will receive your current @_ as its parameters. This can lead to very hard to spot errors.
Is it just that I should use the hash in my code as opposed to assigning the hash values to a variable and then using the variable instead?
Indeed. Why assign to a hash first when you're going to put it into a variable afterwards? Using a hash also is usually cleaner, since it provides an own little name space for the variables in question; it keeps together what belongs together, and keeps them from littering the global namespace.
What exactly does the $|=1 do?
It disables buffering for the currently selected filehandle (which would usually be STDOUT). See perlvar.

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!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
