<br>Flags: Undocumented function<p>
<pre><b>INT 21 - OS/2 v2.1+ Virtual DOS Machine - UNLOAD DOSKRNL SYMBOLS & LOAD PROGR</b>

	AH = 64h
	DX = 0006h (function number)
	CX = 636Ch (magic value, "cl")
	BX = 0000h (indicates special request)
	ES:DI -&gt; ASCIZ filespec
	DS = base address for loading
Notes:	if CX is not 636Ch on entry, INT 21/AH=6Ch is invoked, because a bug
	  in OS/2 1.x FAPI erroneously called AH=64h instead of AH=6Ch
	this function is only supported by the kernel debugging version of
	  OS2KRNL
