Category: <b>DOS kernel</b>
<br>Flags: callout or callback (usually hooked rather than called), Undocumented function<p>
<pre><b>INT 2F - MS Windows WINOLDAP - SWITCHING ???</b>

	AX = 4602h
Return: ???
Note:	the DOS 5+ kernel intercepts this function and copies the
	  previously-saved MCB from the DOS data segment into the MCB following
	  the caller's PSP memory block; in conjunction with AX=4601h, this
	  intercept is used by DOS to avoid corruption of the Windows real-mode
	  heap's end sentinel
