RE: Default numeric: zoned or packed

Barbara, 

That worked great.  I also made that external data structure BASED(@).
Thanks for the help and information.

I've read a lot of articles and threads (here or in archives) that

On our system, it defaults to Zoned.
Is there a system setting involved here?

I recently created a data structure that had file-defined fields (so I

only had the name of the field in the DS, no definition) and it 
converted all my Packed numbers to Zoned (which of course caused my 
calls to unprototyped programs to fail).

The solution I had was to explicitly define the numeric fields in the 
data structure (which I don't like doing b/c now if one of those field

definitions changes, someone has to fix the data structure).  I 
considered using ExtFld, but, near as I can tell, that only works with

a ExtName - and I don't want all the fields from that file in the data

structure.

 
Kurt, for maximum confusion, when the type of a numeric field is not
specified for a _subfield_ it defaults to zoned.  See the "Internal
Format" section of the "Data Types and Data Formats" in the ILE RPG
Reference.

I think the easiest way to solve the problem would be to define your
subfields LIKE subfields in an externally-described data structure that
you define just for the LIKE definitions.  Using the LIKE keyword, you
get the new field defined exactly the same as the like field.  (Beware
that this is not the case for *LIKE DEFINE.)

D myfile_types    e ds              qualified extname(whatever)
D myds              ds
D    something                      like(myfile_types.somefield)
