-- CHECK THAT LENGTHS MUST MATCH IN ARRAY AND SLICE ASSIGNMENTS.

-- THIS IS A SPECIAL CASE IN
-- DIVISION C : NON-NULL ARRAYS WHOSE LENGTHS ARE NOT DETERMINABLE
-- STATICALLY
-- WHICH TREATS ARRAYS OF LENGTH GREATER THAN INTEGER'LAST .
-- AN ADDITIONAL OBJECTIVE OF THIS TEST IS TO CHECK WHETHER LENGTH
-- COMPARISONS (AND LENGTH COMPUTATIONS) CAUSE
-- CONSTRAINT_ERROR TO BE RAISED.
