-- OBJECTIVE:
--     CHECK THAT CONSTRAINT_ERROR IS RAISED FOR 'SUCC' AND 'PRED',
--     IF THE RETURNED VALUES WOULD BE OUTSIDE OF THE BASE TYPE,
--     WHEN THE PREFIX IS A FORMAL DISCRETE TYPE WHOSE ACTUAL ARGUMENT
--     IS A USER-DEFINED ENUMERATION TYPE.

-- HISTORY:
--     RJW 06/05/86  CREATED ORIGINAL TEST.
--     VCL 08/19/87  REMOVED THE FUNCTION 'IDENT' IN THE GENERIC
--                   PROCEDURE 'P' AND REPLACED ALL CALLS TO 'IDENT'
--                   WITH "T'VAL(IDENT_INT(T'POS(...)))".
