<br>Flags: Undocumented function<p>
<pre><b>INT 21 - DOS 4.0+ internal - COUNTRY-DEPENDENT FILENAME CAPITALIZATION</b>

	AH = 65h
	AL = function
	    A0h capitalize filename character
		DL = character to capitalize
		Return: DL = capitalized character
	    A1h capitalize counted filename string
		DS:DX -&gt; filename string to capitalize
		CX = length of string
	    A2h capitalize ASCIZ filename
		DS:DX -&gt; ASCIZ filename to capitalize
Return: CF set on error
	    AX = error code (see <a href=../../it/80/16.html>#01680</a> at AH=59h/BX=0000h)
	CF clear if successful
Note:	nonfunctional in MS-DOS 4.00 through 7.10 (Win98) due to a bug (the
	  code sets a pointer depending on the high bit of AL, but doesn't
	  clear the bit before branching by function number).  Supported and
	  functional(!) in Novell DOS 7 (Update 15), as well as PC-DOS 7 and
	  OS/2 MVDM
