Re: page up/page down issue

Mike,
I would suggest that you use separate command keys on the subfile control
record for previous/next record.
The Page Up/Page Down keys in the subfile will not return control to the
program until either the user attempts to page up/down before the first
record or after the last record in the subfile.

Booth,
There are 2 programs. The initial subfile program which you would select
a '5' on a subfile record to display the detail record(via a second
program).

The second program depending on the type of record in the subfile will
display either a Display File(RECORD) or a Display File(SUBFILE)

If the Display File(RECORD) is displayed, you can press page up/down to
show subsequent records(its essentially the same effect as selecting many
subfile records at the same time and processing them sequenctially.

However if the Display File(Subfile) is displayed, the page up/down
keywords are associated with subfile, so all I can do is page through the
subfile, I can't get to the next record. The subfile is a load all
subfile, so I don't need the page up/down for the subfile.

I hope I am explaining it better now

Mike

Subject: Re: page up/page down issue

I am not clear on how many formats/programs there are. A main screen
format with 2 maintenance window formats, one with a subfile?

In any event, one thought is to use
SFLEND(*SCRBAR *MORE) ***
with the subfiles and let users use a scrollbar to move the subfile(s) up
and down. That allows scrolling by a a few rows or a lot of rows.
http://www.martinvt.com/Subfiles/Two_Subfiles/two_subfiles.html

As to the specific problem: is there code in the DDS for page up/page
down? If so, what happens if you comment that code out? I ask that
because my memory tells me that with subfiles, the less code the better.

Are you processing 2 formats at once, with a write followed by am
exfmt/read?

*** it really is that simple as long as you leave 3 empty columns at the
end of the subfile row.

I'm having a little issue with page up/down that I'm not quite sure how

to handle.

This is a basic RPG CRUD application.
The way we code these mimics our vendor supplied code

Display a subfile
Select option to edit/display a record.

Say I have 20 records in subfile and I place a '5' in an option field

to display the maintenance screen.

I can press page up/down in the maintenance screen to continue looking

at subsequent records.

So far so good. Now to the problem.

With this particular application, I can have 2 different maintenance
screens display The normal screen that displays all the fields.
Or a second screen that is a subfile screen.

Now my page up/down seems to be attached to my subfile and I am never

able to page up/down to a subsequent record.

Any ideas how I can handle this?

Thanks

Mike
