I just tested that, and it doesn't seem to work. The abs calls wern't really redundant because you needed to test the greater value displaced from 0, so when you have two negative values -5 < -4 but you still want -5 returned. :)

UPDATE: Well done with the update, it works nicely when i tested it, i liked the use of the sub too, i only wish the game of golf had a longer time limit so i could have played around with some of these ideas for longer,

• 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.
