I can't believe you people are still coding subfiles!

The one thing that has not been mentioned with respect to the different
type of subfiles is that a load-all subfile retains the data since the
initial load all.
If the user is in that data for any decent amount of time, then the
original data could have changed and no matter how many times that you
page-up and/or page-down (or position to) the data is STILL old
A page at a time sub file should always give you the latest data each time
you page-up, page-down or position to

Each type of subfile has their pro's and con's
Which one to choose depends upon what the business need is as well as how
much work the programmer wants/needs to put into the task
