| -- |
| -- 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. |
