    if ($error) {
        print "Errors detected in specifying options.\nUsage:<usage string>";
    } else {
        ### Rest of the code
        if ($opt1) {
            if ($info[1]==1) {
                ### If the value is a default value
                print "Default value for opt2 is taken\n";
            } elsif ($info[1]==3) {
                ### If the value is not default
                print "Non-default value as given = $opt2";
