National Language Support Codes

When you use commands to set up your system for a national language, DOS makes sure the screen, printer, and keyboard codes you request work together. The valid combinations of prepared code pages, country codes, and keyboard codes are defined in the COUNTRY.SYS and KEYBOARD.SYS files. The supported combinations are listed in Table B–3.

Both Swiss French and Swiss German use country code 041. Country codes 358 and 972 assume United States code page 437, but include country-specific date and time conventions. For example, if you use country code 351 (Portugal), you can use prepared code pages 860 and 850 and the po (Portugal) keyboard code. You could not use the us (United States) keyboard code. If you enter a country code 002 with a us keyboard code, DOS displays an error message when you restart the system.
