Hello

I am using the following code to try and determine if a column has any data other then 0 

#!/perl/bin/perl.exe -w

use strict;

my @array = ();
my @row = ();
my %hash = ();

if ( @ARGV != 1 ) {
    print "\nUsage: <File Name> \n\n";
    exit(0);
}

my $file = $ARGV[0];

open (FILE, $file) || die "ERROR: Unable to open $file :$!\n";

@array = <FILE>;
my $size = @array;

for (0..$size) {
    @row = (split /\;/, $array[$_]);
    $hash{$_} = \@row;
   
    foreach (@row) {
    print $_, "\n";
    }
    @row = ();
}

I know have a hash of row data, How can I determine if the entire column consists of zero data?
