+--     VARIANTS CAN BE GIVEN OVERLAPPING STORAGE.
+
+-- HISTORY:
+--     PWB 07/22/87  CREATED ORIGINAL TEST.
+--     DHH 03/27/89  CHANGED EXTENSION FROM '.DEP' TO '.ADA' AND
+--                   ADDED CHECK FOR REPRESENTATION CLAUSE.
+--     RJW 06/12/90  REMOVED REFERENCES TO LENGTH_CHECK.  REVISED
+--                   COMMENTS.
+--     JRL 10/13/96  Adjusted ranges in type definitions to allow 1's
+--                   complement machines to represent all values in
+--                   the specified number of bits.
