Re: main difference between expandable and singlepage subfile

For a couple or so editable fields I keep those field's original values as hidden fields in the subfile. The processing subroutine includes a loop for the subfile where it check for changed value(s) and does a normal update routine. This fits nearly all scenarios for me as I keep subfiles limited in editable content. And yes, adding a processing subroutine does add code.

Yes, I also think that completely editable subfiles are some very special case which rarely applies.

But I don't understand about your second sentence. Do I guess right that you're talking about a READC for the SFL? And UPDATE changed records in the SFL?

The other solution, for more involved edits, is a separate editing program outside the subfile program.

Ah, here's the difference. For small and simple PF editors, I do all in one (*PGM and DSPF), to have all in one place.

Adding a new customer, for instance, is not suited to subfiles.

Depends. The WRKUSRPRF USRPRF(*ALL) SFL has an empty first line for adding (in this case) an user profile. Sometimes. IBM does it like that and sometimes, there's an "F6=Add". I have not yet found out which parameters lead to the decision which variant to use.

Make one program with all the editing, validations, warnings, etc. in one place and let subfiles access it. Let the deletions and additions happen there.

I agree with you if there's more than just edit/copy as OPT values. I generally do delete in the same *PGM. It's not much code and its easier to handle file exceptions one by one to retain failed deletes in the "are you sure you wanna delete" SFL.

All that's my personal opinion and I still consider myself a rookie with just 10 years of private tinkering with my AS/400 and V4R5 (with some extended time without doing anything in between). But I have a deep knowledge as a Linux Sysadmin and also somewhat experience in programming in general. So maybe it's helpful for me to not be encumbered with preconceptions about how stuff should be done because everybody else did so for decades.
