( #3333=superdoc: print w/replies, xml ) Need Help??
I have the book Learning Perl in it there's a section called "Using Scalar-Producing Expressions in List Context" then it goes on to say "Going this direction is straightforward: if an expression doesn't normally have a list value, the scalar value is automatically promoted to make a one-element list:
@fred = 6 * 7; #gets the one-element list (42) @barney = "hello" . '' . "world";
In the first example, the array @fred on the left hand side of the operator = makes it a list context, did i got it right? In the second example, "hello" . '' . "world; alone is a scalar expression? Is the array @barney on the left hand side of the operator making it into list context like the first example?

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.
