in thread define a hash-value, using hash-ref and a list of keys

Hi Rolf, this is what I needed... having an older perl-version,I used for my $key (@keys) { $href = $href->{$key} = {} unless defined $href->{$key};} is this notation {} having a specific usage or name ? Anyway, many thanks for the suggestion !!!

Your code won't work as expected, because of low precedence of `unless` . Either use parentheses or a ternary operator. Better have a look at Re^2: define a hash-value, using hash-ref and a list of keys if Perl < 5.10 is an issue. `{}` is an anonymous hash (-ref).
