Re: Questions about S/36 files

I am a huge proponent of DDL over DDS but for compatibility reasons you
may wish to stick with DDS if you decide to externally define this file
without changing all the underlying RPG. And the reason is that DDL will
enforce data integrity while DDS does not. If you internally define a DDS
defined file and stick characters into a numeric field it cares not a
whit. DDL will stop you cold. And there were a lot of S/36 type
applications which would say stuff like "the vendor supplies a Zimbabwe
currency conversion field but we don't need that but we need to store 4
characters, let's overlay that field". You could get away with that on a
DDS defined file but that is not allowed on a DDL defined file.
