Good catch on the quotes around the filename. I intentionally left it all uncommented. But lets have some more fun with it:

#!/usr/bin/perl -w
use strict;
use IO::File;
use constant FILENAME => 'filename';

{
  package cntr;
  sub TIESCALAR{bless[pop],__PACKAGE__} 
  sub FETCH{ $_[0][0]++ } 
}

my $file = IO::File->new( "< ". FILENAME )   
    or die "Failed to open '@{[FILENAME]}', $!"; 
        
my @elements;
{
    local ( $a, $/ ) = $/.$/;
    @elements = split $a => <$file>;
}
$file->close();

print "Here are the elements of the array:\n";

tie my $i, 'cntr', 1;
print map {$i.': {'."$_}$/"} @elements;

Yeah, that would go over well with a teacher or professor.

Update: So I changed the code a little from the original post. I actually tested it, and didn't like the way the newlines hung around. This fixes that. View source for the old code.

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.
