I'm not too sure what your code is supposed to be doing. It looks a bit like you're trying to count the number of times a particular value occurs in an array. The normal way of doing this is to use a hash:
#!/usr/bin/perl
use warnings;
use strict;
my @ID = qw/1 1 1 1 1 1 1 2 2 2 2 2 3 3 4 4 4 4 5 5 5 5 6/;
my %counts;
foreach my $id (@ID) {
$counts{$id}++;
}
while(my ($num, $count) = each(%counts)) {
print "$num : $count\n";
}
But you might be trying to do something more complicated than that. Some more explanation of what you're trying to achieve would help

It's not easy to juggle a pregnant wife and a troubled child, but somehow I managed to fit in eight hours of TV a day.

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).
