Here's another approach that you might find instructive:
my $text = "0 X X X ..."; my @items = split(' ', $text); my @array; while (@items) { push(@array, [ splice(@items, 0, 8) ]); } pp \@array; use Data::Dumper;
The basic idea is:
  1. Split the input string into an array (@items).
  2. Remove the first 8 elements of @items, create an array ref out of those elements, and push that array ref onto the end of @array
  3. Repeat step 2 until @items is empty.

To make sure you have a full matrix, you can check the length of the last row with:

die "incomplete last row\n" unless (scalar(@{$array[-1]} == 8);

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.
