Get Uppercase Table (Function 6502h) returns the address of the uppercase table for the specified code page and country code. The table maps the extended ASCII characters (characters with ASCII values greater than 128) to their uppercase equivalents.
CodePageID
Identifies the code page to return the uppercase table 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 console/screen.
CountryCode
Specifies the country code to return the uppercase table 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 |
| 033 | France |
| 034 | Spain |
| 036 | Hungary |
| 038 | Yugoslavia |
| 039 | Italy |
| 041 | Switzerland |
| 042 | Czechoslovakia |
| 044 | United Kingdom |
| 045 | Denmark |
| 046 | Sweden |
| 047 | Norway |
| 048 | Poland |
| 049 | Germany |
| 055 | Brazil |
| 061 | International English |
| 351 | Portugal |
| 358 | Finland |
If this parameter is 0FFFFh, MS-DOS returns the table for the current country.
Table
Points to a buffer in which MS-DOS places the 8-bit identifier (02h) of the uppercase table and the 32-bit address (segment:offset) of the table. The buffer must be at least 5 bytes long.
If the function is successful, the carry flag is clear and the 32-bit address of the uppercase table is copied to the buffer pointed to by the Table parameter. 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 buffer size specified by the CX register is less than 5.
This function returns 0002h (ERROR_FILE_NOT_FOUND) if MS-DOS cannot retrieve country information for the specified code page and country code.
The uppercase table starts with a 16-bit value that specifies the length of the table; the remainder of the table specifies the uppercase equivalents of the ASCII characters from 80h to 0FFh.
