Sorry Booth, I already suggested that. The user needs the ability to see
multiple records on the screen.
With the user having the ability to sort the data down in whatever way
they desire, it will help them to "cluster" like items together, so that
they can choose like items for the same Category/Sub-Category.
Like I said before, I didn't say that this project was easy.
However, I hope nobody misconstrues any of my remarks, because the
responses I have received from EVERYBODY, has shown me just how important
that this e-mail group/list is in pooling knowledge.

A subfile has a limit of 9999 records. Its easy to program to stop at
that limit, but really, at that point a subfile has little use. Thats
why I suggested a filter earlier. Later I saw your post where the users
need to process all the records. Well, ok. But they aren't going to
process 65,000 in one sitting. If they really are going to process all
of the records, one after another, why display 10 at a time, anyway?
Display them one record at a time, and allow the page keys to page up
and down through the main file, one record at a time? Then, have the
various possible sorts set on by F-key(s) and use logicals as was
suggested by someone earlier.

Thanks,
I've never used it, but I "wrongly" assumed that it was designed so that
you could do more than 9,999 records.

Michael,
The DDS Manual specifies that a program to system field should be 5S0 if
used for these keywords. But, it also quite explicitly states that the
maximum number of records in a subfile is 9999.

the

for
a hidden field but instead of using an H, you would use a P. The biggest you can define this field is 5, 0 (it may be the only size that you can specify).

Re: Even more embedded SQL.... Thank you EVERYBODY 08/03/2006 12:25 PM Please respond to RPG programming on the AS400 / iSeries <rpg400-l@midrang e.com> Booth - you and I must be on the same wavelength, or in mutual mind-meld mode or something. I want to take time to thank everyone who has replied to my question,withsuggestions, ideas, thoughts, other questions and especially examples. I think I have a handle on everything that I need in relation to what is required for SQL and Dynamic sort building, but what bothers me is the position to aspect of SQL, where the file data is rebuilt, with the
first
record being equal to or greater than the value that was requested to be positioned to. The problem of paging up from that point (before the
first
record) will mean yet another re-creation. So I was thinking of a couple of things 1/. Load the first 9,999 records into a load all sub-file. If the user wants to go above that, recreate the data and load the next 9,999 records etc. etc. If the user wants to position to a value AND its within this 9,999 NO PROBLEM If its outside the range , recreate the data and load the applicable9,999records into the sub-file. 2/. Create a file (via DDS) with all the fields defined COL1, COL2, COL3, COL4, COL5, COL6, COL7 and an additional field which
is
in effect equal in size to ALL the fields CONCATENATED. This field would now be the key of the file, and depending upon what sort is required, build this field accordingly for example if the sort is COL1, COL2, COL3, COL4, COL5, COL6, COL7, the this key field is created as COL1 concat COL2 concat COL3 concat COL4 concat COL5 concat COL6 concat COL7 and then use regular RPG to handle the page up, page down, position to page-at-a-time sub-file Anybody any thoughts on either of these 2 ideas?

08/03/2006 11:40 Re: Even more embedded SQL.... AM Please respond to RPG programming on the AS400 / iSeries <rpg400-l@midrang e.com> May I make a suggestion here? A small, but very helpful step might be to put filters in place before the process starts, or at any time in the process. Let the user set the filters with an F-key. Point out to the users the problems it solves for them, and I believe they will get on board. "I want all of zip code 12345 sorted by color" becomes a breeze to do. If they will filter so that the number of records of interest remains below about 2500 records then you can do a load-all into an array and the sorting becomes a piece of cake. Heck, it even allows a scroll bar, which really is wonderful if for no other reason than that they can pull the subfile up or down one record at a time with no coding required on your part. (Yes, thats right. One record at a time up or down. Piece of cake.) Alan Shore wrote:That's one thing I'm still playing around with in my head. I've talkedwiththe user, and even he's not sure what he wants here. I'm leaning more towards starting from the beginning of the file (Nomatterhow its sorted, for each RE-SORT)as I'm pretty sure this will be easiertocode for.

Lets say I have a subfile sorted by year and the first displayed record happens to have a value of "White" in the color column. When I click the color column does my new subfile start with "White" or with the lowest color alpha value, say... "Amaretto" or "Blue" or "Cyan"?

Do you want the 15 items shown by column "year" to be sorted by color, or so you want all 15000 records sorted by colorfirst,then by year?
