AW: convert dds to ddl

["Birgitta Hauser" <Hauser@xxxxxxxxxxxxxxx>]

At V5R4 you no longer need to replace the PF with an LF because the RCDFMT
clause was added to CREATE TABLE...
It was not necessary before either, as long as you created the table with
the desired format name first and renamed it to the desired file/table name
after ;).

Mit freundlichen Grüßen / Best regards

As I said in my very first reply. At V5R4 you no longer need to replace the 
PF with an LF because the RCDFMT clause was added to CREATE TABLE...
