I'm trying to write a module that allows you to put an array through a routine that will pause it when the screen's full of text. If you type in a b before conitinuing it will go back a screen. If you type a x it will stop printing. However, I'm having a bit of trouble. I can only get it to go back once, and once you type in b you have to hit enter twice. I just started Perl a couple months ago and this is my first time with a module. Here's the code: 
package Text::Break;
$VERSION = 1.1;
sub break() {
    local ($extra, $num, $extra2, $extra4, @text, $status);
    local $text = \@_;
    shift @$text;
    $text3 = @$text;
    if ($text3 =~ /,\s/) {
        ($text, $num) = split ", ", @$text, 2;
    } else { $num = 24 }
    local $counter = 1;
    $status = "yes";
    $extra2 = 0;
    &printer;
    sub printer() {
        undef(@text);
        while ($extra2 <= $#$text) {
            $text[$extra4] = $$text[$extra2];
            $extra2++;
            $extra4++;
        }
        $extra4 = 0;
        foreach $line (@text) {
            if ($counter%24==0 && $status == "yes" && $counter != 0){
                print "--more--";
                $extra = <STDIN>;
                if ($extra =~ /^[bB]/ && $counter != 24) {
                    $extra2 = $counter - 48;
                    undef($status);
                    goto &printer;
                    goto LAST;
                } elsif ($extra =~ /^[xX]/) {
                    goto LAST;
                }
            }
            print $line;
            $counter++;
            $status = "yes";
        }
    }
    LAST: if($extra) {
    }
    1;
}

thanx for any help, I hope this is easy to understand the module's Text::Break, to call it use the break method. The code should be self-explanitory.
