Dear Monks:

I need to write a file with the name of several variables and its values, here's my code:

#!/usr/bin/perl
use warnings;

@pizzas=qw
(
    pizza_margherita
    $cheese
    $tomato
    $mass
    $USERNAME
);
#And 50+ variables...

$cheese="cabrales";
$tomato="orlando";
$mass="secret";
$USERNAME=$ENV{USERNAME}; #Loads Windows environment variable USERNAME
+ value

$n = @pizzas; #loads total of array elements

open (my $variables, "> C:/temp/variables.txt") or die "Bad Luck...";

for (my $i = 0; $i <= $n; $i++)
{
    print $variables "$pizzas[$i]=$pizzas[$i]\n";
}

#I also tried that with the same result
#foreach (@pizzas)
#{
#    print variables "$_=$_\n";
#}
close variables;

Gives me this faulty variables.txt output:

pizza_margherita=pizza_margherita
$cheese=$cheese
$tomato=$tomato
$mass=$mass
$USERNAME=$USERNAME

[download]

Desired variables.txt output:

pizza_margherita=pizza_margherita
$cheese=cabrales
$tomato=orlando
$mass=secret
$USERNAME=windowsuser

I have to work with the array variable contents because there are hundreds of arrays with 50+ variables each, I read dozens of posts and tried several methods but it always returns the variable name instead of its contents, how do I may proceed?

Thanks! Regards :)
