Not to digress to far but the difference between Forth and many other
languages is the interface to words is not independently enforced. The
effect is the series effects of sequential words. I once did a lot of work
making real time applications work reliably, a lot of it was simply
segmenting code into well defined pieces and restructuring applications
to improve the reliability numbers of the application. This is the stuff
of heated discussions.

Interesting numbers on your PDP 11 app It suggests the real cost
of conditionals.
