Some other interesting discoveries. The meaning of the 'unregistered' error
has to do with calling an invalid operator code that indexes an uninitialized
slot in the "command table". There is an internal "loop" type object that is
used as a sentinel on the exec stack to delimit a loop's frame, making an
easily searchable target for the 'exit' operator.

Some discussion has also started in comp.lang.c in a thread by Bart about typedefs.
