I just want to clarify that my step was two fold.
1 - Use real dates. Now, this can be done via SQL's DDL or via DDS.
2 - Use DDL. DDL checks at write time for errors. DDS leaves it up to
the language to check at read time, or even worse, when it actually tries
to use the field. So DDS does allow the data to get corrupted. If you
define with DDL you can't take a simple text file and CPYF it over the
file and get bad dates and numerics. With a file defined via DDS you can.
