This is the correct way into the LZ World application from machine code
- do not search the main menu for "World" and its address, as its name
changes in multi-lingual versions.
- Function 0 - Initialises the world application. It sets the base to
be London, Paris or Bonn depending on the language byte (btb_lang).
The initial city is always set to New York Manhattan.
- Function 1 - Runs the world application exactly as in the top level.
- Function 2 - Gets the base city and country names into the run time
buffer. Returns with the city name at rtt_bf+100 and the country name
at rtt_bf+120. Both are length byte strings. If the current base is
a country (so there is no city) then the country is promoted to the
city field and the country field is blank.
