| -- OBJECTIVE: |
| -- CHECK THAT, FOR A CONSTRAINED IN FORMAL PARAMETER HAVING AN ACCESS TYPE, |
| -- CONSTRAINT_ERROR IS RAISED IF AND ONLY IF THE ACTUAL PARAMETER IS NOT |
| -- NULL AND THE OBJECT DESIGNATED BY THE ACTUAL PARAMETER DOES NOT SATISFY |
| -- THE FORMAL PARAMETER'S CONSTRAINTS. |
| |
| -- HISTORY: |
| -- RJW 10/28/88 CREATED ORIGINAL TEST. |
| -- JRL 02/28/96 Removed cases where the designated subtypes of the formal |
| -- and actual do not statically match. Corrected commentary. |
