Re: Can you use a DDM data area with i5_data_area_read?

Hmmm... I see I forgot to include the link to the Create Data Area command which describes the layout of the creation data presented by the Display Data Area of a DDMDTAARA [the object Attribute of a DDM DataArea; see RTVOBJD OBJATR()] when requesting SYSTEM(*LCL) against a DDM data area. FWiW:
http://publib.boulder.ibm.com/infocenter/iseries/v6r1m0/topic/ddp/rbae5crtdt.htm

Noted additionally there is the "Retrieve Data Area (QWCRDTAA) API", which like RTVDTAARA, has no option to get the *LCL data presented by the DSPDTAARA command; i.e. like CHGDTAARA, these all default to [and will only] act on the target\remote data area, in contrast to the DSPDTAARA default.

To test the data area interactively, use DSPDTAARA SYSTEM(*RMT)
[or RTVDTAARA and DMPCLPGM, debug, or otherwise, or CHGDTAARA and
view the updated data area on the target system]. The shipped
default for DSPDTAARA is SYSTEM(*LCL), which as you noticed, is
not very helpful. FWiW I was [similarly] disappointed to find its
default was not SYSTEM(*DTAARATYPE), or some other special value
available to effect similar to the special value *FILETYPE on the
QDBRTVFD API. Instead of adopting my point of view, it was just
pointed out that SYSTEM() of DSPFD defaulted to *LCL and although
it supported *ALL [which does not fit with DSPDTAARA design] but
no *FILETYPE. :-(

I tried this with a DDM data area and I did not get anything returned.

When I switched it to a data area that resides on our box, it worked fine.

Did not see anything in searching, but did read that DDM can be
used. I have DDM files and they are ok. I know that the DDM
data area seems to be a different animal. When you view it, you
do not see the actual data area but attributes of how it was
created and such.
