in reply to A Case with 5 Var's
Use a hash instead of five scalars. Then you can do:
my @found; foreach my $field_name (qw/name vorname plz tel tel49/) { push(@found, $field_name) if ($my_hash{$field_name}); }
(Untested)
That will give you an array of all the fields that are set. This may or may not be helpful - you didn't say what you planned to do with the results.
