Err, no. When I replied to your post, it only dealt with numbers as elements. You've since changed your post by adding the second program. Here is a demonstration that the first version of your post does not work for text:

#!/usr/bin/perl

#my $text = '1,2,3,4,5,6,7,8';
my $text = 'a,b,c,d,e,f,g,h,i,j';

my (@even, @odd);
push @{ $_ % 2 ? \@odd : \@even }, $_ for split /,/, $text;

print "odd = @odd, even = @even\n";

__END__

output (first $text):
odd = 1 3 5 7, even = 2 4 6 8

output (second $text):
odd = , even = a b c d e f g h i j

• 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.
