Re: convert dds to ddl

Yes, he meant RNMOBJ LIB/RCDFMT *FILE TABLE after CREATE TABLE LIB/RCDFMT to 
get a table named TABLE with RCDFMT(RCDFMT). wow...

Driving to London is much quicker when you don't go via Brighton, so the 
addition of RCDFMT to CREATE TABLE at V5R4 did make it easier :)

For tables?!?!  Sparked my curiosity!  Is this done via after-the-fact
RNMOBJ or something else?  Do tell!
