Re: subfile problem

["Dan Bale" <dbale@xxxxxxxxxxx>]

There are good cases for specifying a page-at-a-time that also adds to an
existing subfile list of records (sflsiz = sflpag + 1), however in the case
being explored here (and we still need to hear back from Jigna as to whether our
assumptions are correct), I think that Jigna should explore clearing the subfile
with each page up or page down action (sflsiz = sflpag), especially if paging up
"beyond" the top of the subfile is an issue.  Considerations:  Are there input
fields that need to keep their data when paging through the subfile?  Or can you
force action on those inputs before handling a page request?  If this is a
simple inquiry, then sflsiz = sflpag should suffice.

Jigna does not specify what causes his (my apologies if Jigna is a woman's
name) performance problem, but he does give us a clue. Since he has no code
to handle a pageup request, the user must start at the beginning of some
group of records (perhaps some customer's history) then page through all of
the records until reaching the one the user was looking for in the first
place. In this case, the number of records in the file is very relevant. A
customer with 10,000 records will take a long time to page through at five
records per page.

If this is the problem, one solution would be to allow the user to start
somewhere in the middle of some group of records (perhaps some customer's
history after a given date), but now the lack of a pageup becomes more of
an issue. It can be very confusing and frustrating to a user when an
artificial boundary is created. I know it's a pain, but you really should
not ignore the pageup request.
