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

That doesn't do what my code does at all, which is to avoid the need to fix the array by transposing it by creating it right in the first place. From the point of view, your code is a step backwards. If you wanted to change my code to avoid pushing, then you'd do

my @data; while (<>) { my @fields = split ' '; my $col = $. - 1; for my $row (0..$#fields) { $data[$row][$col] = $fields[$row]; } }

Tested.

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.
