In DDS I can define FILEA with a Zoned numeric field with size 5/2.
In DDS I can define FILEB with a Packed numeric field size 5/2, using
REFFLD as the Keyword to refer to the Zoned field in FILEA. I make the
field in FILEB Packed by placing a "P" in column 35. That will define a
new field in FILEB with the same size as the referenced field in FILEA but
make FILEB's field Packed instead of Zoned.

How do I do that in DDL? I do not want to redefine the field in DDL as
DEC(5,2).

But I think that is the way you specify packed:

https://www.ibm.com/docs/en/i/7.3?topic=elements-data-types

The docs are a little confusing because in the prose, they tend to use
the word "decimal" to refer to the node in the chart that is parent to
both "decimal" and "numeric" terminal (leaf) nodes.

But the chart makes it pretty clear: "decimal" means packed and
"numeric" means zoned.
