  25 -- OBJECTIVE:
  26 --     CHECK THAT OVERLOADING RESOLUTION USES THE RULE THAT:
  27 --
  28 --     FOR EACH INTEGER TYPE, THERE EXISTS AN IMPLICIT CONVERSION THAT
  29 --     CONVERTS A UNIVERSAL INTEGER VALUE INTO THE CORRESPONDING VALUE
  30 --     OF THE INTEGER TYPE. THIS TEST USES LITERALS AS UNIVERSAL INTEGER
  31 --     VALUES.

  33 -- HISTORY:
  34 --     TRH 08/11/82 CREATED ORIGINAL TEST.
  35 --     DHH 10/20/87 SHORTENED LINES CONTAINING MORE THAN 72 CHARACTERS.
