 - `$time_as_str()` - Read the time of day (ingame) as text string in 24h format, like "18:45"
 - `$time_as_num()` - Read the time of day (ingame) as integer number in 24h format, like 1845
 - `$get_input(num)` - Read an input value provided by an external block with the given number _num_. The block has to be configured with the number of the controller to be able to send status messages (on/off commands) to the controller.  _num_ is the number of the remote block, like "1234".
