RE: [EXTERNAL] Re: Fwd: main difference between expandable and singlepage subfile

Hi Jay
You will be surprised!
I have had to change quite a number of load all subfile programs to a page at a time subfile programs, because the total number of records to display surpassed 9,999
And this number WAS valid
Import export systems was one of the main culprits
The number of parcels that had yet to be investigated by customs, far exceeded 9,999, depending upon the time of year
Could the system have been created better to start with, to circumvent this situation in the first place
Oh yeah
But unfortunately - I had to work with what I was given

why anyone would write a more complex page at a time subfile these days is beyond me.

A "load all" with a filter input field is all that should EVER be needed.

No way a user should be asked to scroll through 9999 subfile rows to get to the record they are seeking.

Historically data traveled at much slower rates. IBM needed a means
to get that first screen of data in front of a user asap and thus the
expandable subfile was born. Programmers could push out the first
screen or two of data quickly, and then as the user paged up/down, new
screens could be added as needed. With the ability to add filters and
starting points a user would rarely need to scroll more than a few
screens. All in all a win-win for everyone. Cumbersome for the
programmer, yes, but it saved tons of band width.

With today's speeds and drill-downs the expandable subfile becomes, in
my opinion, anachronistic.
