this will throw and lead back to the outer-interpreter.
traditionally, the outer-interpreter is called QUIT
in forth itself where the first part of the QUIT-word

and then turn to an endless loop containing QUERY
and EVALUATE (otherwise known as INTERPRET )
- in pfe the primary cleanup is done through a longjmp
due to the implicit THROW .
