( #3333=superdoc: print w/replies, xml ) Need Help??

The list for core perl is everything from UNIVERSAL.pm and up. SUPER is also in the core and is frequently used. The other things are still somewhat uncommon. You would be wrong to think that only 'VERSION' is the available method. When I load my perl up with no modules at all and look at in the debugger I get four methods.

perl -dea DB<1> m main via UNIVERSAL: DOES via UNIVERSAL: VERSION via UNIVERSAL: can via UNIVERSAL: isa DB<2> q

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 or How to display code and escape characters are good places to start.
