Hey guys i've created a game kind of thing which generates a random integer between 1 'n' 100. User has to guess it and at the end it saves the score in a file called high_score.dat. I had to edit the program so if an existing user, plays the game only his score his changed, but it doesn't work. It doesn't show any errors but it has a semantic error. Here's the code Please HELP ME: 
open FILE, "high_score.dat";
while (1){
    while defined($score = <FILE>){
    print "$score\n";
    }
    $num = int(1 + rand 100);
    print "If you want to exit type 'quit' or 'exit' or leave a blank 
+line\n";
   INPUT_TAKER: { $count++;
    print "Guess a num: ";
    chomp ($guess = <STDIN>);
    if ($guess == $num) {
    print "Right!!!.\n";
    print "enter youre name: ";
    chomp($name = <STDIN>);
     while defined ($line =  (<FILE>)){
        if ($line =~ /^($name)/){
        $line =~ s/\d+$/$count/;
        }
        else{
        open FILE, ">>high_score.dat";
        print FILE "$name has the score of $count\n";
 
        }
    }
    print "You took $count chances to complete\n";
    
    
    }
    elsif ($guess =~ /^(exit||quit||\n)$/){
    last;
    }
    elsif ($guess > $num){
    print "High!!!. Go lower \n";
    redo INPUT_TAKER;
    }
    elsif ($guess < $num){
    print "Low!!!. Go higher \n";
     redo INPUT_TAKER;
    }
    
    }
    if ($guess =~ /^exit||quit||\n$/){
    last;
    }
    
}
print "Thank you for playing my game\n";
