Please don't tell people to use $a just so they can avoid having to properly declare a real variable name. $a is a piss-poor variable name in general, completely antithetical to writing clear code, and the only reason that works is because of magic which you didn't bother to explain - magic which would one day bite the new guy in the ass if he took your ill-conceived advice and made a habit of using undeclared $as and $bs on a regular basis.

If you're really fixated on not having to properly declare your variables, it's much saner to turn strict off. And "it's much saner to turn strict off" is not something I say lightly, it's a reflection of just how astonishingly bad the advice "change your variable name to $a so you don't have to declare it" is.

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



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
