Yes I have seen it, and you aren't kidding about it taking a while - that document is almost 800 pages of I-don't-know-what-I'm-looking-for! The screen I am attempting to re-create is not a complicated one (no windows or tabs or dropdowns) - I am just trying to establish a maintainable format. I have seen only two mentions of trying to create a setup like this and I think they both came from web developers trying to work with green screens (and of course the results were not posted). IBM documentation has not been helpful to me, unfortunately, because anything written with modern application design in mind does not use DDS for the UI.
I can get two screens to display at once with the information available, but I cannot determine how to have a set of default file-level keywords and available function keys that I could add to every screen I make (without copy-paste). I think this would require having both the base screen (with the defaults set) and the main screen "active" at the same time, but it seems it is only possible to have a single screen active at a time (is this what you mean when you mention using windows? Do they allow the function keys from the screen below to remain active?). Either that, or there is maybe some way to set these parameters in the RPG before the EXFMT? Otherwise, I believe my only option is a precompiler.
Thanks,
Sarah

Sarah - have you seen the "Application Display Programming" manual from IBM? It would answer most of what you are asking, although it might take you a while to get to each area.
But there are examples there of doing various things that might help you.
You are going from web to 5250 - the usual thing today is from 5250 to web, and often parts of the 5250 screen are parceled out to index tabs, say, to give better landscape.
Now it is possible to have windows overlay a screen, and those windows can have the smaller bits or the things you would have had in tabs - maybe that's a way to go - take your tabs and make DSPF windows of those, then assign F-keys to make them be displayed over the main screen.

Thanks for the explanation. In this scenario, is there a way to set the file-level keywords and available function keys in one file and use them across the whole application, or do their definitions need to be present in each display file? Is there some way to set these with RPG or do they have to be compiled in with the DDS?--
Thanks,

The best I've ever been able to do to accomplish what you're trying to do, is to divide each "working section" of the screen into a separate display file with its own program and overlay the screens. So I have Program A that calls program B to clear the screen and display header and footer sections and then calls one of several programs in some order that overlay the middle section with perhaps a subfile or other entry form. Those programs restore the screen and return information to Program A. Program A records the information and determines which program to call for the next "subscreen". Also use "popup" screens for choosing one of many values, for instance; one can reuse the same program and display file for many kinds of lists.
You can also accomplish the same thing with many "records" in a display file managed by a single program.
The old rule was one display file per program, but newer versions of RPG allow a display file per sub-procedure.

It's true I'm coming from a web background. I can't remember the last
time I made a page that was actually all located in one file so I am
trying to get these green screens working with the same flexibility.
I'm looking for a combination of CSS and a PHP (or ASP) 'include',
which just grabs the header file (which could have standard config,
output, and style information) and adds it to the page. I am ok with
this 'grab' being at compile time rather than runtime, but I really
don't like the idea of just having a template that I copy and paste into each new screen... what if something changes?
I'm really struggling with the limitations of DDS. I did see this preprocessor:
http://rpglanguage.biz/copybook.html. Not being very familiar with
iSeries terminology, it sounds like it might be capable of allowing a /COPY in my DDS.
Has anyone had any experience with something like this?
Thanks,
Sarah

Sounds like she's trying to do a DDS version of Cascading Style Sheets (CSS).

Subject: Common Display File (Header + File-level Keywords)
I learning about RPG and DDS for screens and I am trying to determine
if there is some method of including or referencing one DDS screen
inside of another. What I want to be able to do is create a "common"
display file that has, for instance, the company name and the date,
and includes some file-level keywords and allowed function keys
(INDARA, CA03, etc.). Then, ideally, I would be able to create
program-specific screen content in a separate file without having to
redefine the common function keys, header information, and file-level keywords.
Is there a method of including DDS source with something like a
/copy? Or can I use two display files in one RPG program and have
their allowed keys and keywords both active at the same time? I have
tried using two in one program, but I can only get them both to
display by using EXFMT rather than WRITE for the header file, which
means control needs to be returned before the main screen is written.
If I use a WRITE header followed by an EXFMT main screen, only the
main screen is displayed and none of the file-level keywords from the header are active.
I have also seen advice to designate a header field in your display
file and customize it in your program in order to allow a more
standardized header, but I don't know how (or if) it can be used with
file-level keywords and allowed function keys?
If this is not possible, how is screen standardization usually handled?
Thank you,
Sarah
