Re: Representation clause in records?

[Steven Hovater <nh-ho@mediaone.net>]

The only rep spec I"ve seen is an alignment clause at the beginning of the record,
e.g. (best I can recall...)
type foo is record
   for foo'address use at mod 32;
   begin
     blah : integer16;
     more_blah : integer16;
end record;

cheers,
Steve
