Point of fact...you've _always_ been able to get a DDL created table
to have a record format ID of a DDS created physical.

With the addition of the RCDFMT clause in v5r4, it became easier. But
it could be done before.

My understanding was that I needed DDS Logicals to get the same format

It appears that with 6.1 that isn't the case, in that DDL (SQL) defined
files will have the same format id as the DDS physicals and logicals.

I have tested the "GENDDL" tool, and have proven that it will generate
the SQL that matches the fmt ID of the DDS files.  So this means that I
don't have to create logical files out of my old physicals.

I will create new SQL indexes prior to re-creating my old logicals.
what else can/should I do to my logicals?

Were you thinking about recreating your logicals in DDS, but first create
indexes?  I do not see a reason to use DDS to recreate your logicals.

Some indexes you may not have but which may come in handy ...
If you have select/omit logicals (which you can do just fine in DDS on
6.1) like this
CREATE INDEX ROB/gqcyl1
ON ROB/GQCY
(MUVALUE)
WHERE RECID='A'

Then you may also want an index like this first
CREATE INDEX ROB/gqcyl2
ON ROB/GQCY
(recid, MUVALUE)

I think this will help performance of queries over the base table which do
something like
SELECT ...
FROM GQCY
WHERE RECID='A'...
And I think you want those created first.
