( [id://3333]=superdoc: print w/replies, xml ) Need Help??

But why does Dump show "a", "b", "c", "d" and not \"a", "b", "c", "d"? It seems to show an ordinary array. You don't need to dereference anything in the following basic array:

[ "anna", "beth", "christie", "denise", ] foreach my $girl (@arr) { print "$girl\n"; }

... and if it's a ref to an array instead of an array itself, shouldn't Dump show \... in my original post? It looks as if it's an ordinary by-value array because there's no slash in front of it to point out it's a reference.

Thanks!

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.
