Using goto is generally considered to be bad style as it can make your code hard to follow. Consider re-coding the above snippet without using a goto, eg: 

#! /usr/bin/perl

use strict;
use warnings;

sub get_input {
    print "Type R to re-enter the values or Type E to exit:\n";
    chomp (my $value = <STDIN>);
    $value;
}

my $value = get_input();
while ($value ne 'E') { 
    if ($value eq 'R') {
    $value = get_input;
    } else {
    print 'Invalid entry, please try again\n';
    get_input;
    }
}
exit();

My cow-orkers were talking in punctuation the other day. What disturbed me most was that I understood it.
