perl: storing regex in array variables trouble

hi
this is an example of code:
Code:
use strict;
use warnings;
open FILE, "/tmp/result_2";
my $regex="\\[INFO\\] Starting program ver. (.*)";
my $res="Program started, version <$1> - OK.\n";
while (<FILE>) {
if ($_ =~ /($regex)/) {
   print "$res";
    }
}
close FILE;
This finds $regex and print out the $res, but "$1" doesn't work. I've tried <\$1> as well and other variations. How to make it work?
