I am new to programming and I have chosen PERL to learn. I have the book "Teach yourself PERL in 21 days" I am on day 3, and I have decided to create some small scripts to practice. I created a script that asks for your hourly pay rate and calculates your yearly salary. I also made one in reverse. The problem I am having is combining them. I am trying to get it to ask "Do you wish to calculate yearly salary (y) or hourly rate?(h)" If you enter h it performs the hourly to yearly calculation, if you choose y it performs the yearly to hourly. If you dont choose h or y it asks you again. I am stuck in a proverbial loop. Here is my code 
#!/usr/local/bin/perl -w

$input = '';    #temporary input
$hrate = 0;    #pay rate
$yrate = 0;    #yearly salary


while () {
    print 'Do you wish to calculate yearly salary (y) or hourly rate?(
+h)';
    chomp ($input = <STDIN>);
    if ($input eq '') { last; }
        
        
    if ($input =~ /h/) {
        print "Enter your hourly rate:";
        chomp ($hrate = <STDIN>);
        $yrate = ($hrate * 40) *52;
    
        
        }
     }print "Your yearly salary is $yrate";
