Hi i am trying to adapt a code from last week to give me all co-ordinates above a specific threshold in this case 500 

 #!/usr/bin/perl
use Modern::Perl; #does an implict use strict; use warnings and activa
+tes "new" features
no warnings qw /uninitialized/;

my @result;

{ 
    open my $INPUTFILE, '<', '/Users/ts/input.txt' or die "File error:
+ input file: $!";
    while (<$INPUTFILE>) {
        chomp; 
        my ($index, $value) = split /\t/; 
        $result[$index] = $value;
    }
} 

{ 
    open my $OUTPUTFILE, '>', '/Users/ts/output.txt' or die "File erro
+r: output file: $!";
    while (my ($index, $value) = each @result) {
        next if $value > 500;
        say $OUTPUTFILE, "$index\t$value"; 
    }
} 

input.txt
1 10
2 11
3 9
4 500
5 550
etc

i am trying to create an output which will give me a file with all values above 500 for example currently it is not generating anything at all in output.txt and just shows all values in terminal and not just those co ordinates above 500 i can't see what i am doing wrong thank you for your time
