   --------------------------------------------------------------------------

     You can get extended country information with this function. It both
     supercedes and returns more information than function 38h.

     To use it, DX must contain the ID of the country. Place a subfunction
     number in AL from the following list:

              Subfunction   Action
              ----------    ----------------------------
                  1         Get country information
                  2         Get address of character table
                  4         Get address of filename character table
                  6         Get address of collating sequence
                  7         (DOS 4+ only) Get address of DCBS vector table

     This function returns information in a return buffer, which is is set up
     differently for different subfunctions. See the information above for the
     buffer format by subfunction.

        Notes:        The NLSFUNC DOS extension must be installed to get
                      information about countries other than the currently
                      installed country.

     Subfunction 01h returns the same information as does function 38h,
     but it also includes the current code page and the country ID
     information. See the structure of the return buffer above.

     Subfunctions 02h - 06 return five bytes. The first byte is the
     subfunction number (02h - 06h). The next four bytes make up the address
     of different types of tables.

     Subfunction 02h returns the address of a translation table used to
     convert extended ASCII characters (codes 128 - 255) to characters with
     codes 0 - 127.

     Subfunction 04h returns the same type of table as Subfunction 02h,
     but this table is used for filenames.

     Subfunction 06h returns a table that specifies the collating sequence
     for the current code page.

     Subfunction 07h is only available in DOS 4+. It returns the address
     of the current DBCS table. DBCS tables can vary in size. They consist
     of a one-word length field, followed by one or more pairs of bytes:

                        TABLE_SIZE      DW      2 * n
                        1               DB      START,END       ;DBCS vector 1
                        2               DB      START,END       ;DBCS vector 2
                                        :
                                        :
                        n               DB      START,END       ;DCBS vector n
                                        DB      0, 0            ;Marks end

     The DBCS byte-pair table is used to translate characters in non-ASCII
     character sets (which must use two byte codes).
