RE: Single Page/Expanding/Load all subfile USAGE

Well this should be on the RPG list but, I would do a page at a time with
position to.  Just remember to load the subfile with out locking the
records.  I like to read one extra record so I can set the more/bottom
correctly.  I also like to retain the RRN or some data base forced unique
key to chain out and do the necessary update.  You can even keep the
original data in a multi-occurrence data structure for such thing as
changing the unique key or auditing.

I have a question regarding usage of Single page/Expanding subfile/Load all
subfile.

The program i need to write is supposed to have an update subfile.The number
of records may exceed 9999.
Which type of subfile should one go keeping in mind performance, record
locking , retention of changed values  issues.
