Exactly, buy definition prototyping is predaclaring functions and the allowable arguements for that function.

What you were doing is only defining them and the args at the point you use them, that's only half the picture. Predefining them allows the complier (in this case the interpreter) to make certain assumptions about the calls to the function and error out if they are wrong.

One other point that should be made is that there are reasons NOT to prototype in Perl. Do a search on this site and you will come up with several nodes that debate that very point.

"Nothing is sure but death and taxes" I say combine the two and its death to all taxes!

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.
