Really? I would have thought such use of integers created a huge potential
for abuse. For example,
with Text_io;
procedure Nonsense is
Last_OK_Date : constant := 99_12_31;
Last_Balance : constant := 3_000;
begin
Text_io.Put_line (Integer'Image (Last_OK_Date + Last_Balance) );
end;
I think I'll stick to records (or Eiffel classes) for composite types composed
of numeric identity data such as dates, part numbers and Social Security numbers.
Don.
