Yes, just do an Interrupt 25 (which is 19h).  That will do it nicely.

One minor comment: rebooting a computer is a pretty harsh way to recover
from a program error.  In fact, with today's windowing systems, by rebooting
the system you could cause a nasty problem for another program.

A Scenario:
	a) I am in Lotus, and decide to run your program.

	b) I do a shell escape.  Then run your program.

	c) Your program crashes, and causes a reboot!

	d) All my Lotus data is lost, since I didn't save it before
	   shelling out.

Just a friendly point.
