Actually the 400 started out as the Least Common Denominator of the S/38
and the S/36.  There were a lot of features in the S/36 that were sorely
missed, (at least until DDS was dumped for SQL).  For example, you could
define a file in IDDU and restrict the values for certain fields.  Then if
you ran the S/36 equivalent of UPDDTA it would prevent you from doing so.
When we migrated that to the AS/400 that was dropped.  The DDS keywords
that were supposed to do the same thing were only there to make SDA try to
adopt some of these for screens.  They were ignored by UPDDTA.  Now SQL
with constraints seems to have plugged that glaring hole.

Actually the core of OS/400 at the time was from the S/38... goes back
even FURTHER :-)
