Get Extended Country Information (Function 6501h) returns the country information that MS-DOS uses to control the keyboard and screen.
CodePageID
Identifies the code page to return the country information for. This parameter can be one of the following values:
| Value | Meaning |
| 437 | United States |
| 850 | Multilingual (Latin I) |
| 852 | Slavic (Latin II) |
| 860 | Portuguese |
| 863 | Canadian-French |
| 865 | Nordic |
If this parameter is 0FFFFh, MS-DOS returns information about the current code page for the keyboard/screen.
InfoSize
Specifies the size of the buffer for the country information. The buffer must be at least 5 bytes long.
CountryCode
Specifies the country code to return information for. This parameter can be one of the following values:
| Value | Meaning |
| 001 | United States |
| 002 | Canadian-French |
| 003 | Latin America |
| 031 | Netherlands |
| 032 | Belgium |

| 048 | Poland |
| 049 | Germany |
| 055 | Brazil |
| 061 | International English |
| 351 | Portugal |
| 358 | Finland |
If this parameter is 0FFFFh, MS-DOS returns information about the current country.
Information
Points to a buffer that receives country information. The buffer consists of a single byte followed by an EXTCOUNTRYINFO structure. The EXTCOUNTRYINFO structure has the following form:
EXTCOUNTRYINFO STRUC
eciLength dw ? ;size of the structure, in bytes
eciCountryCode dw ? ;country code
eciCodePageID dw ? ;code-page identifier
eciDateFormat dw ? ;date format
eciCurrency db 5 dup (?) ;currency symbol (ASCIIZ)
eciThousands db 2 dup (?) ;thousands separator (ASCIIZ)
eciDecimal db 2 dup (?) ;decimal separator (ASCIIZ)
eciDateSep db 2 dup (?) ;date separator (ASCIIZ)
eciTimeSep db 2 dup (?) ;time separator (ASCIIZ)
eciBitField db ? ;currency format
eciCurrencyPlaces db ? ;places after decimal point
eciTimeFormat db ? ;12- or 24-hour format
eciCaseMap dd ? ;address of case-mapping routine
eciDataSep db 2 dup (?) ;data-list separator (ASCIIZ)
eciReserved db 10 dup (?) ;reserved
EXTCOUNTRYINFO ENDS
For a full description of the EXTCOUNTRYINFO structure, see Chapter 6, “National Language Support.”
If the function is successful, the carry flag is clear and the country information is copied to the EXTCOUNTRYINFO structure. Otherwise, the carry flag is set and the AX register contains an error value, which may be one of the following:
| Value | Name |
| 0001h | ERROR_INVALID_FUNCTION |
| 0002h | ERROR_FILE_NOT_FOUND |
This function returns 0001h (ERROR_INVALID_FUNCTION) if the value specified in InfoSize is less than 5. If the InfoSize value is greater than 5 but less than the size of the country information, the information is truncated and no error is returned.
This function returns 0002h (ERROR_FILE_NOT_FOUND) if MS-DOS cannot retrieve country information for the specified code page and country code.
Function 38h Get/Set Country Information
Function 6601h Get Global Code Page
Function 6602h Set Global Code Page
