If I recall correctly (and I may not seeing as how it's Friday afternoon

and, more importantly, I'm a geezer), IDDU was a pain in the rectal area

to use.  However, consider the lack of a database on the /36, it was the

only way that I remember to write queries.


As painful as it was, it was a decent start for some /36 programmers to 
start "designing" databases.  There was, I think, the ability to use a 
reference file of sorts. 


But, then, even a kid in high school can do SQL and DDS.  It took a 
/real/ programmer to do IDDU.  Definitely not for the weak hearted.

The last time I used a *DTADCT on the iSeries was when working in

S/36 mode

(that was a quick in/out and run gig). It basically allows you to

define

fields for s/36 flat (program described) files so that you can then

use

things like query/dfu etc. to access the data as fields instead of

one large

field. I can't remember well, but you may even be able to use the

data

dictionary to cause the compiler to treat the file as externally

described,

but can't be sure of that.

A *DTADCT, while conceptually similar to, is not the same as a field
reference file by any means. A *DTADCT causes the system to present

the flat

file as a file with fields.

At least that's my recollection...

Crispin.
