The Territory Manager and UK Territory

Q: What is the Territory Manager?
A: The Territory Manager is a new RISC OS 3 module providing control over
   the localized aspects of the computer. The Territory Manager can have
   more than one Territory module loaded at any one time but only one can be
   the active Territory for the computer.

Q: What is a Territory module?
A: A Territory module (such as the UK Territory module present in the RISC
   OS 3 ROM) is a module providing the Territory Manager with information
   about a specific Territory (such as the UK). This information includes
   things like the time zone, the language used, the keyboard layout used,
   which character to use for the decimal separator, the collation order
   for characters, the writing direction for the local language, and more.

Q: What is the current Territory?
A: Each computer running RISC OS 3 has a value for the current Territory
   stored in its CMOS RAM. This value controls the Territory that is used by
   the system. This is the current Territory of the computer. The current
   Territory controls such things as the language used to display menus, and
   the default time offset from UTC. There can only be one current Territory
   for any one computer.

Q: Why is there only one current Territory?
A: Since the current Territory controls such things as the language used for
   menus. It would be very confusing to have, for example, some of the menus
   appear in one language and some in another language. In the UK, even if
   you are editing a German document you would normally want the menus to
   still appear in English.

Q: If there is only one current Territory, why should it be possible to have
   more than one Territory loaded by the Territory Manager?
A: While there can only be one current Territory for any one computer, some
   applications written for RISC OS 3 may wish to be able to include text in
   two different languages in the same document. It is useful for such an
   application to be able to read the information relating to both languages
   at the same time.
