Re: Data Dictionary

The CRTDTADCT command creates a data dictionary for IDDU. IDDU was a S/36 
product that could be used to enable users to create queries over S/36 
style flat files. We never used it any place I worked because it simply 
created more work for programmers without any benefits to us. Many old 
S/38 programmers may have used the term data dictionary to refer to a 
field reference file. You may want to ask however assigned this to clarify 
their requirements.

Re: Data Dictionary






I'm sorry if I wasn't clear. It is a Iseries shop, true blue. Old school. 
I was told to do a data dictionary. Now, I did create it, but am not sure 
what to do with it. The PF is not going to relate to it on the REF line.
  A                                      REF(REFFILE) 
  this is for a file.
 
  The dd is not a file.

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.
