The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Yes. This is the way RPG works. It converts all numeric fields from
files into packed (unless you tell it not to.) That way, you can use
the same field names in multiple files, and they'll all have the same
definition.
For example, if you have a CUSTMAS (Customer Master) file and a DDS
display file that's intended as a place to edit the customer master
record. You can use the same field names in the display file as you do
in the CUSTMAS record. So you don't have to manually move every field
from CUSTMAS to the display... you can just read the CUSTMAS file, and
it'll automatically populate the display fields.
The same works for any type of file (display, printer, database,
communications, tape, etc). So you can read a record from one file and
write it to another.
The idea is to convert everything to a common format -- to facilitate
this idea of sharing fields between files.
This is the way that RPG has worked since RPG III was introduced on the
S/38.
Note that if you declare an external data structure, or you read your
database file into a data structure, the rules change. When you do
this, RPG will stop trying to convert things to packed, and will use the
same definition that's in the database.
