Int 21 Fn 65  - Dos 3.3+ - Get Extended Country Information                [D]

   AH = 65h
   AL = info ID
       01h get general internationalization info
       02h get pointer to uppercase table
       03h (DOS 6.2+ COUNTRY.SYS) get pointer to lowercase table
       04h get pointer to filename uppercase table
       05h get pointer to filename terminator table
       06h get pointer to collating sequence table
       07h (DOS 4.0+) get pointer to Double-Byte Character Set table
   BX = code page (FFFFh=global code page) (see #1446)
   DX = country ID (FFFFh=current country)
   ES:DI -> country information buffer (see #1439)
   CX = size of buffer (>= 5)

Return: CF set on error
       AX = error code (see #1366 at AH=59h/BX=0000h)
   CF clear if successful
       CX = size of country information returned
       ES:DI -> country information (see #1439)

Notes: AL=05h appears to return same info for all countries and codepages; it
     has been documented for DOS 5+, but was undocumented in earlier
     versions
   NLSFUNC must be installed to get info for countries other than the
     default
   subfunctions 02h and 04h are identical under OS/2
   subfunction 03h apparently supports only codepage 866 in DOS 6.2x
