Hi, I wrote a small piece of code to extract a table of values from a file into a hash but it's giving me a weird output. What am I doing wrong? 
#!usr/bin/perl
use strict;

open (FILE,'<abc.txt');
my %config;

while(<FILE>)
{
    if($_=~'^(\w+_?\w+)=([01])')
    {
        $config{$1}=$2;
        print "$1:$config{$1}\n";
    }
}
close FILE;
for my $i (sort keys(%config))
{
    print "$i:$config{i}\n";
}

This is the output I get: 
$ perl test002.pl
AAA:1
BBBB:0
CCC:0
DD:1
AAA:
BBBB:
CCC:
DD:

And this is the sample input file: 
AAA=1;
BBBB=0;
CCC=0;
DD=1;
