-- OBJECTIVE:
--     CHECK THAT OVERLOADING RESOLUTION USES THE RULE THAT:
--
--     FOR EACH INTEGER TYPE, THERE EXISTS AN IMPLICIT CONVERSION THAT
--     CONVERTS A UNIVERSAL INTEGER VALUE INTO THE CORRESPONDING VALUE
--     OF THE INTEGER TYPE. THIS TEST USES LITERALS AS UNIVERSAL INTEGER
--     VALUES.

-- HISTORY:
--     TRH 08/11/82 CREATED ORIGINAL TEST.
