I'm not sure you need the NEXT key, won't the last key do? Whave we've done
before is send the direction (next/previous) and the last key received last
time (if next) or the first key received last time (if previous) and let the
server figure out what to send back. IF you have a single "surrogate" key
it's just one parm, if you have a composite key... Well it's more parms <G>

Agreed.

That's the plan, alas the original is a subfile and positioning subsequent
pages is an issue.  Well, it's an issue for me.

I think we may have been able to convince the customer that a complete list
in HTML is not as useful as a search mechanism would be.  Between that and
the ability to download the entire list as a .csv file, they should be all
set.
