Hello Master,

I'm stuck with these code in which im having trouble printing data with referring hash values. Can anyone help me. It'll be helpful.

#!/usr/bin/perl
use strict;
use warnings;
use diagnostics;

use Data::Dumper;

# Define Files and assign strings 
my $DIN_CAP = "0.0005";
my $DIN_PWR_ARC = "0.000000,0.000000,0.000000,0.000000,0.000000,0.0000
+00,0.000000,0.000000";

sub mainCSV 
{
    # Open the CSV input file
    open (my $infile_CSV1, '<', "$infile_CSV") or die "Unable to open 
+$infile_CSV: $!\n";
    my %hash  = (); 
    my $hash_ref = {};
    
    while (my $line = <$infile_CSV1>) 
    {
        chomp;
        $line =~ s/\s*\z//;
        my @array_CSV = split /,/, $line;
        my $key_CSV = shift @array_CSV;
        if ($hash{$key_CSV})
        {
            warn "Duplicate key '$key_CSV'";
        };
        $hash{$key_CSV} = \@array_CSV;
    }
    
    # Explicit scalar context 
    my $size = scalar keys %hash; 
    # Prints Number of Pins (Hash size...)
    print "Number of Pins: $size\n"; 
    
    # Open the output file and save hash in $outfile_RX_CSV
    open (my $outfile2, '>', "$outfile_CSV") or die "Unable to open $o
+utfile_CSV: $!\n";
    print $outfile2 Dumper(\%hash); 
    close $outfile2;
    print "Stored $size list of pins in $outfile_CSV file.\n";
