I am not here to start a DDS versus SQL war but I have a 
question I am hoping you can help me hash out.

You cannot add PF constraints using DDS.  I have some files 
that I've built using DDS and then added RI on the files using 
the ADDPFCST after they were built.  I am afraid that collegues 
will modify the files and when they recompile all of the Referential 
Integrity will be lost.  I was thinking that it would be safer 
to define the files using SQL and write an SQLRPGLE program to 
rebuild them.  I document the RI in the DDS but who reads that?
