Hi, I have a REALLY newbie question. I want to ask a question from the cmd line and get the answer in. But I want to validate the answer. I have this so far but it seems like far to many lines for what should be a simple thing. 
#! perl.exe
print "Please enter you name:\n";
chomp ($name =<STDIN>);

&answer();
exit;

sub answer()
{

print "Hello $name.\nWill you be joining me for a swim? [Y/N] \n";
chomp ($_=<STDIN>);
    
if (/^[yn]/i)
    {
        if (/^n/i) 
            { 
                print "Begone, evil peon!\n"
            } 
        if (/^y/i)
            {
                print "YIPPEEE.!!!!\n";
            }
    } else {
        # Validate user input and return message if invalid
    print "\n\n=====================================\n";
        print "You Have Entered and Incorrect Option\n";
        print "Valid Options are [Y/N]\n";
        print "=====================================\n\n";
        &answer;
    }
}

My above code also validates Yesterday as true and never as false. I only want to match [Yy]es, [Nn]o or just [Yy] or [Nn].
