Here's how I modified your code:

#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };
use v5.10;

sub view_all_railcars {

    say "View All Cars";
    *MYINPUTFILE = *DATA{IO}; # To simulate the input.

    my $viewlines = 4;

    print "=====================\n";
    print "|CAR MODEL|CAR OWNER|\n";
    print "=====================\n";

    while (<MYINPUTFILE>) {
        chomp;
        my ($VcarModel, $VcarOwner) = split /:/;
        $_ //= q() for $VcarModel, $VcarOwner;

        if ($. > 1 and $. % $viewlines == 1) {
            <>;
        } else {
            print "\n";
        }
        my $format = "         %-13s %0s\n";
        printf $format, $VcarModel, $VcarOwner;
    }

    print ("\n\n\nWHEN YOU ARE DONE VIEWING HIT RETURN: \n\n\n");
    do 1 until defined <>; # Do not end on CTRL+D
    say 'cls';
    say 'Menu';

}

view_all_railcars();

Hello choroba,
Thanks for your updated code it does the trick. I'm still a little confused between the 'foreach' and 'while' operations. In my case the 'foreach' statement just displayed the data while the 'while' statement allowed me to manipulate my data. Thanks again.
