RPG does indeed ignore the default value setting on the fields.  RPG has
always worked this way.  See "Using Output Specifications" in the
"Defining Files" section of the Programmer's Guide where it talks about
creating a new record: "Fields not specified in the output field specs
or not meeting the conditions specified by the output indicators are
written
as default values, ... (for example: a blank for character fields ...)".

ILE RPG allows you to initialize an externally-described data structure
with the default values using INZ(*EXTDFT).  You could use the subfields of
such a data structure to set the fields that you don't want to output, and
then output them.

(This scheme would not work for dates that default in the database to the
current system date since the data structure is initialized when the
program
starts and the date might change; you would have to use the TIME opcode to
get the current date for each record.)
