The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

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.
