	Here's the code.  I adapted this from Borland C++ code and it
worked.  I didn't test the SetMouseInfo() function, but I think it works.

	If anyone has some (tested) code for sending your own
mouse-handler function to interrupt 0x33 (ah=0x0c).  The FAQ (Section 18.8
How to make DOS/BIOS call your function) has a version, which I've tried
to impliment, but it just crashes my computer whenever it tries to call my
function.  Thanx.
