Encoding and decoding

Encode cities and airports

Part 1 Encode cities and airports

TRANSACTION CODE	CITY NAME
DAN	PARIS

Shown above is the entry to encode a city name. The purpose of this entry is to determine the three-letter code for a specified city and its corresponding airport(s).

If a city has only one airport, the city code and airport code are usually the same. If the city has more than one airport (multi-airport city), the codes for each airport will be displayed.

This entry will also display codes for other types of transportation locations within the city, such as railroad stations and bus terminals

This entry consists of the transaction code DAN, followed by the name of the city you wish to encode. It may be helpful to remember the transaction code as "Display All (by referencing a) Name".

In application, the entry shown above would display the three-letter codes for the city of Paris and its airport(s), as well as any other associated location codes.

The city name must be entered exactly, and spaces where appropriate are required. For example, the city name "Los Angeles" must be entered with a space, like this: DANLOS ANGELES.

The entry begins with the transaction code "DNS", followed by the country code "US" and the two-letter state code.

In application, the entry shown above would decode the US state with the code CA

The last two entries may also be used for provinces. An entry such as DNSAU may be used to determine the provinces or states within a country.
