<p>In apparatus which supply characters or symbols and which are intended for service in different countries, some characters of symbols must have different forms for different countries or groups of countries, In the case of read-out apparatus which reproduce in dots, such as matrix printers or displays, the character forms are usually stored in a read-only store, a given address being assigned to each character. In order to achieve simple addressing in the case of a character which has different forms in different countries, not the character form ins stored in the corresponding storage location, but rather one or more addresses which indicate in which location in the character store the relevant, country-dependent character form is prosent. To this end, each storage location comprises an additional storage (bit) position which indicates whether or not address information is concerned and which is in principle read and interrogated first. Depending on the contents of this storage position, either the remainder of the store is than read and transferred to the read-out or an address in the address control system is read and transferred; after that the special character form stored at this further address location is read.</p> |
