File maintenance app using page-at-a-time subfile and SQL

After about a 9 year hiatus from interactive app development, I started a
new job this week where I'm back into this.

Was given a project for an existing maintenance app that currently loads a
page at a time, adding to the subfile with each page down action, until it
hits the 9999 limit. Problem is, now we're starting to get transaction
data that exceeds 9999 records.

The new design I suggested is to redefine the subfile using SFLSIZ=SFLPAG,
and each paging action performs editing on the entire page of records, then
updates the table when there are no errors. The current app has a
"position-to" entry, and we need to be able to page both up and down from
that position.

SQL is not mandatory at this point, but I can see a potential future
benefit of being able to select certain records for display/maintenance.

I've searched for example templates, but the few I've found are for inquiry
only and not using SQL. Some websites linked in the archive are now
non-existent. If anyone knows where I can find a decent template, please
let me know.

TIA,
