Well, actually, not running, I am sort of trotting, maybe briskly
walking, into SQL and JAVA. ;) It's the whole print thing and stuff like
level breaks that are holding me back. I still have a lot of RPG/CL/DDS
clients to support, but I am given liberty (without budget) to try out
different approaches.

I'm in total agreement with you about the merits of what IBM has given
us as tools on the AS/400, but, IMHO, the world isn't going to stay the
same for us dyed in the wool IBM midrangers much longer.

Maybe when I get up to speed on SQL I'll have a better appreciation for
the "missing" parts you mention.  But, again, I stand by the premise
that if you have your own tool for data definition, you can control the
creation of DDS or SQL (of any flavor or limitation) and not have to
worry or care about if IBM makes enhancements to DDS, which I think is
what started this discussion.

Sorry,  but I think that the energy would be better spent on having
IBM's SQL implementation enhanced so there are no "missing" parts and
while they are at it toss in REFFLD capability and raise the bar for all
implementations of SQL.

Within this thread, Eric N. Wilson posted what may be a workable
solution to the REFFLD issue.  My problem has not been with the use of
SQL as an alternative to CHAIN, but in the definition of the file
itself.  As I understand it, referential integrity can only be
implemented on those files that are created via SQL.  RI is my goal, but
I didn't want to trade one benefit (RI) at the cost of another (REFFLD).

Personally I could care less about -how- I must define a file, my issue
is whether I can automate the process.  With the proper tools, you can
become platform or implementation independent.  IMHO, DDS is just a
particular platform, and from what you tell me, IBM's SQL is just a
particular implementation.

To sum up my view point, I'm amazed at how a software community spends
more energy on protecting their methods or languages than they do on
creating the tools of the trade.  Maybe my view point was slanted by my
first mentor that made a simple, yet profound (to me anyway) statement:
"Programs -are- data."  For a compiler writer a source program is the
input, for a tool writer the program is the output.  The same can be
said for DDS or SQL or IDDU or whatever the world throws at us next.
