If it was for MS-DOS, you would need to make it a TSR.  This can be done
using Interrupt 21h, function 31h or interrupt 27h.  You then need tomoniter
the keyboard interrupt ( 09h ).  Exactly how that is done, I am unsure, but
you should be able to find some examples on the net.  As a note, hwoever, be
aware thast if it is active while another program is running, there could be
serious side effects if you are not careful.  Also, some MS-DOS programs
 mostly games ) replace the standared keyboard handler, which may make your
screen saver become active during play, not to mention the screen saver may
seriously corrupt the video display.
