use constant EMPTY => 0; $bottles{beer} = 99; sub take_one_down { return --$bottles{beer}; } sub pass_around { print "No more beer\n" and exit($bar) if ($bottles{beer} eq EMPTY); } print "$bottles{beer} on the wall\n"; while ($bottles{beer}) { take_one_down($bottles{beer}); pass_around($bottles{beer}); print "$bottles{beer} on the wall\n"; }

Actually takes the beer off your wall.

UPDATE: Since I am seem to be getting some flak. I decided to write this one in an effort to be slightly more visually poetic while still running. Of course there are many ways to do it (that's what makes Perl so great), I just wanted something up there that read more poetically.

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.
