IDDU with OS/400

["Philippe BOUSSAROQUE" <ph.boussaroque@xxxxxxxxxx>]

Hi all,
new  in OS/400(AS170 V4R3 & 3 AS/36 Virtual machines),
I am discovering this system.
With S36 I was using  IDDU for describe my files in order to QRY them
or/and transfer DATA from S36 to PC(for example under PCS36 with TOPC)
Under OS/400 in emulation mode(STRS36), if I link the files to the same
dictionary as in S36  true machine(previously loaded via RSTS36FLR), I can
continue to QRY files as before but file transfer do not use the IDDU
descriptions. The description used in this case is the automatic description
of 1 field (2 if keyed file: key + data) of total length=length of the file.
If I want to transfer as before , I have to describe the file in a file
object via a source member type PF in QDDSSRC  + compile.
Curiously(?!) if a make a description of a file in DDS mode, I can QRY the
file.
Question:
 IDDU is it still present under OS/400 only for S36 continuity ??
Is it a Command or CL to create automatically the DDS source from IDDU??
Is it a PC software using only IDDU descriptions for selective transfer
under OS/400??

By advance tks for your answers.
(sorry for bad English)
