---
--- OBJECTIVE:
--- Check that Constraint_Error is raised in cases of null arrays when:
--- 1. an assignment is made to a null array if the length of each
--- dimension of the operand does not match the length of
--- the corresponding dimension of the target subtype.
--- 2. an array actual parameter does not match the length of
--- corresponding dimensions of the formal in out parameter where
--- the actual parameter has the form of a type conversion.
--- 3. an array actual parameter does not match the length of
--- corresponding dimensions of the formal out parameter where
--- the actual parameter has the form of a type conversion.
---
--- TEST DESCRIPTION:
--- This transition test creates examples where array of null ranges
--- raises Constraint_Error if any of the lengths mismatch.
---
--- Inspired by C52103S.ADA, C64105E.ADA, and C64105F.ADA.

---
--- CHANGE HISTORY:
--- 21 Mar 96 SAIC Initial version for ACVC 2.1.
--- 21 Sep 96 SAIC ACVC 2.1: Added new case.
