The statement
EXIT
raises the exit-exception. An EXIT statement must be textually enclosed by a LOOP, WHILE, REPEAT, or FOR statement.
We define EXIT and RETURN in terms of exceptions in order to specify their interaction with the exception handling statements. As a pathological example, consider the following code, which is an elaborate infinite loop:
LOOP
TRY
TRY EXIT FINALLY RAISE E END
EXCEPT
E => (*skip*)
END
END
