  25 -- OBJECTIVE:
  26 --     CHECK THAT, FOR OUT PARAMETERS OF AN ACCESS TYPE,
  27 --     CONSTRAINT_ERROR IS RAISED:
  28 --          AFTER A SUBPROGRAM CALL WHEN THE BOUNDS OR DISCRIMINANTS
  29 --          OF THE FORMAL DESIGNATED PARAMETER ARE DIFFERENT FROM
  30 --          THOSE OF THE ACTUAL DESIGNATED PARAMETER.
  31
  32 -- HISTORY:
  33 --     CPP  07/23/84  CREATED ORIGINAL TEST.
  34 --     VCL  10/27/87  MODIFIED THIS HEADER; ADDED STATEMENTS WHICH
  35 --                    REFERENCE THE ACTUAL PARAMETERS.
