Currently has two problems, one easy to fix, the other medium:

(1)	Not obvious how to exit, and on the AMIGA under Lattice C,
	control-C is braindamaged in that it must be explicitly
	enabled.  

(2)	No srand/rand function in Manx C, so only linkable under
	Lattice.  This can be fixed by finding an appropriate
	alternate function in Manx C, or rolling your own.
