You should always try to explain the results you expect and what you
are getting instead. I had a hard time understanding what your problem
was just from reading your message. :)
It looks like your problem is passing the value of $age instead of a
reference to $age. In order for the Getopt::Long module to modify your
$age variable it needs a reference to it:
use strict;
use warnings;
use Getopt::Long;
my $age;
my %opts = ('age=i' => \$age);
GetOptions(%opts) or exit 1;
if(defined $age)
{
print "You specified '$age' years";
}
__END__
You can see perlref and perlreftut to learn about references. You
should also be using 'strict' and 'warnings' (to possibly save Shlomi
a breath ;).
