Here is a somewhat more idiomatic implementation of your code:
use strict;
my %hash;
my $key='NetWallah';
$hash{$key} = [
map{
[ map {int(rand()+0.5)} 0..9 ]
} 0..9
];
printit(\%hash);
sub printit{
my $href=shift;
for my $key(sort keys %$href){
my $row = 0;
print "{$key} =>\n";
for my $rowref (@{$href->{$key}}) {
print " $row\t";
for my $val (@$rowref) {
print "$val ";
}
$row++;
print "\n";
}
}
}
"How many times do I have to tell you again and again .. not to be repetitive?"

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).
