Tic-Tac-Toe, my first script :)

This was my first GUI Perl script.

    my $offset = shift;
    $_=$Player;
    return if ((/-/)||(substr($PlayMap,$offset,1)!~/\s/));
    substr($PlayMap,$offset,1)=$_;
    $bouttons[$offset]->configure(

        -activebackground => (/O/)?'#60F040' : '#F04060');

        if($Player x 3 eq substr($PlayMap,$o1,1) . substr($PlayMap,$o2,1 ) . substr( $PlayMap,$o3,1)){
