Hi Birgitta
I was interested in your reply, because I do more or less the same thing,
but using files in QTEMP. I've looked at dataqueues in passing. Do you find
that using dataqueues instead of files is more efficient, quicker etc.

Hi,
we solve such problems with keyed dataqueues located in the QTEMP library.
Each time page down, page up pressed or if the subfile is positioned to
some
where, we read current the subfile records and store the options other than
*Blanks and the unique key information (or relative record no) of the
subfile record in the dataqueue.
If we fill the next or previous page or whatever page, for we try to
receive
a dataqueue entry for each record we read. If a dataqueue entry is found,
the option is added to the subfile record and SFLNXTCHG is set *ON.
If Enter is pressed, we receive all entries from the dataqueue and handle
them according to the option.
Mit freundlichen Gruessen / Best regards
Birgitta

Jerry, a page-at-a-time subfile is controlled by the program and not by the
subfile. The max number of records in the subfile would only be whatever
you set it be (lets say 10). Not really sure how I could explain this
better.
In order to load the next page, you (well we do) would have to clear the
subfile and write out 10 new records. Thus causing the option column to
be cleared and lost if not processed before going to the next page.
I'd imagine that you could write the first 10 records, wait for the page
down to be pressed, the program will then load the next 10 records. Now
the subfile will handle the page down until the end of subfile is reached.
If at the end of the subfile and page down is pressed again, control will
be passed to the program and the next 10 records could be loaded. Now you
have three pages loaded in the subfile.
But I don't see this as a page-at-a-time subfile. But more like a subfile
that grows with you. However, it would do what you just explained, allowing
you to press page up and page down without losing the option column. I
hope that was clear.
Now if there's some other way to keep that data, I'm all ears. :-)...

Well, I'm confused as to the actual requirement. I use both
page-at-a-time and load-all subfiles with option/select columns. Type
and option (such as '2' or '4') on the subfile line, press PageDown /
PageUp to my heart's content, and the previously entered options are
still there until the /Enter/ key is pressed to process the options.
No special coding. The option field is in the subfile format and is
defined as type 'B' (input/output). The program doesn't even do
anything (other than load the next page stuff) until the /Enter/ key is
pressed. Admittedly I am using RPG IV, not RPG/400, but the process is
the same in both cases.
So, somewhere I'm guessing that the requirement is (to me, anyway)
ambiguous.
