Adding and changing information
Adding a city
If your own home town or city is not known by World, you can add it with the 'Add
city' option. You'll be asked for longitude and latitude. GMT offset (the hours ahead of
or behind London's "Greenwich Mean Time") and zone for summer times. Don't worry
if you don't know all of these — before you choose 'Add city', you can estimate these
from the settings of a city near yours.
1. Find a city near to your own which World does know about.
2. Select the 'Add city' option on the 'Edit' menu. The dialog suggests the longitude and
latitude (etc.) of the city you've just found, and this should be approximately right.
It's worth entering the longitude and latitude because they are used to calculate
distances and sunrise/sunset times.
The 'Add city' dialog looks like this:

3. Type the name of the city on the top line. If you've "borrowed" information from a
nearby city, as suggested above, you can leave the longitude and latitude, and the
GMT offset. If you want to change longitude and latitude, just type the digits
concerned. Wherever the cursor is on the line, you can type W or E for longitude,
and N or S for latitude. Similarly, if you change the GMT offset, you can type +
or - ,
4. To enter the area code, type it as you would dial it when in the country concerned.
5. In general, you should set the summer time 'Zone' for new cities to 'As country'. It
will then have the same summer time as the rest of its country. (If you set this to
'Constant', summer times are ignored for this city.)
6. Press Enter. A flashing marker is now displayed on the world map. Use the <- tJ. -t
keys to move it to the correct position for the new city. To move the marker by
greater distances you can hold down the Control key while using <- Tf When the
marker is correctly positioned press Enter.
Adding' a country
Strictly speaking, you cannot add a new country to World. You can, however, modify
the details of a country that is already there using the 'Update country' option. Before
doing this, it may be helpful to look at a country which you know is near the one you
wish to add, and note its zone for summer times, and its GMT offset. You can then use
these in the 'Update Country' dialog.
1. Select a country, preferably one which you don't expect to use.
2. Select the 'Update country' option on the 'Edit' menu.
3. Enter the details of the country you wish to add. Don't worry which city is shown as
the capital city, for now; you can add the real one later after you have entered it as a
