Re: File and Program field definition

(This question should probably be in a FAQ somewhere)

The RPG compiler will automatically convert ZONED data being input from an 
externally defined file into PACKED,  unless you specifically tell it that
you want your field to be zoned.

This is not a new feature of RPG IV... It did this in RPG III as well.
This just didn't cause many conflicts because ZONED was so rarely used in
RPG III.

Anyway, a simple workaround is to pull your file into an externally
described data structure.  Add a line similar to this:

D MyFileDS      E DS                  ExtName(MYFILE)  

Which will create a data structure with your externally defined fields,
forcing them to be the attributes that you used in your DDS source.

Have Fun!
