Actually, Rascall and the Demo program both use the same method. I
can't tell you anything about it (yes, I do know some about it), but the
part that traps the keys is sort of a program. It's not an interrupt
but it is somewhat similar. My shell will include this feature, as soon
as I get it completely figured out.
