( #3333=superdoc: print w/replies, xml ) Need Help??
It would be reasonable, but it doesn't work that way. In fact here is a piece of code that triggers an illustrative bug in how it does work:
recurse_lex(1); print "\n"; recurse_lex(2); print "\n"; recurse_lex(3); print "\n"; recurse_lex(4); print "\n"; sub recurse_lex { my $i = shift; my @array if 0; unshift @array, $i; print @array, "\n"; $i--; if ($i) { recurse_lex($i); } }
Try that. It does something weird. And here are the details of what does happen.

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.
