sounds interessting, so i need to check the vector bit pattern to generate a matching qry
and this i woud do again with if and co ;/ because i don't know another way

It depends a lot on where you want to go with this. One technique would be to use a hash to generate a dispatch table. Consider:

use strict;
use warnings;

my %dispatch = (
        0b000001 => \&noneTrue,
        0b111110 => \&allTrue,
        0b001101 => \&firstLine,
    );

my $name = '';
my $vorname = 'full';
my $plz = 1;
my $tel = 0;
my $tel49 = undef;

while (<DATA>) {
    chomp;
    
    my ($name, $vorname, $plz, $tel, $tel49) = split ',';

    my $vector = (!$name) || 2;
    $vector |= (!$vorname) || 4;
    $vector |= (!$plz) || 8;
    $vector |= (!$tel) || 16;
    $vector |= (!$tel49) || 32;

    $dispatch{$vector}->($.) if exists $dispatch{$vector};
}


sub noneTrue {
    print "None true in input line $_[0]\n";
}

sub allTrue {
    print "All true in input line $_[0]\n";
}

sub firstLine {
    print "Matched first line pattern at input line $_[0]\n";
}


__DATA__
,full,1,0,
first,second,3,4,
1,2,3,4,5
,,3,4,

last,,,,

Prints:

Matched first line pattern at input line 1
All true in input line 3
None true in input line 5
