```{index} single: store; Config function ``` ```{index} single: Config::store; Perl function ``` # store Tied-hash write: always croaks; `%Config` is read-only. ## Synopsis ```perl $Config{archname} = 'foo'; # dies ``` ## What you get back Nothing. The call raises `Config is read-only` and unwinds to the nearest `eval`. ## Examples ```perl eval { $Config{archname} = 'bogus' }; print $@; # Config is read-only ``` ## Edge cases - The croak fires regardless of the key or value; there is no per-key override. ## Differences from upstream Fully compatible with upstream.
