Hi all,
i've 5 variables and need to check if they are "" or full.
i need to check all possibility of combinations, i've done it with a if elsif construct and i'm asking myself "is there not a nicer way to do it ( without goto)"

my $name;
my $vorname;
my $plz;
my $tel;
my $tel49;


if ($name) {
    if ($vorname) {
        if ($plz) {
            if ($tel) {
                if ($tel49) {
                    $name , $vorname , $plz , $tel and $tel49
                }
                $name , $vorname , $plz and $tel
            }
            $name , $vorname and $plz
        }
        $name and $vorname
    }
    elsif ($plz) {
        if ($tel) {
            if ($tel49) {
                $name , $plz , $tel and $tel49
            }
            $name , $plz and $tel
        }
        $name and $plz
    }
    elsif ($tel) {
        if ($tel49) {
            $name , $tel and $tel49
        }
        $name and $tel
    }
    elsif ($tel49) {
        $name and $tel49
    }
    only $name
}
elsif ($vorname) {
    if ($plz) {
        if ($tel) {
            if ($tel49) {
                $vorname , $plz , $tel and $tel49
            }
            $vorname , $plz and $tel
        }
        $vorname and $plz
    }
    only $vorname
}
elsif ($plz) {
    if ($tel) {
        if ($tel49) {
            $plz , $tel and $tel49
        }
        $plz and $tel
    }
    only $plz
}
elsif ($tel) {
    if ($tel49) {
        $tel and $tel49
    }
    only $tel
}
elsif ($tel49) {
    only $tel49
}
