Re: Fwd: main difference between expandable and singlepage subfile

Or has 5250 usage become insignificant?

It seems that we have this discussion every year in December as people look
toward the future. Sometimes it's more of a discussion about browser user
interfaces, or about application architecture.

From my perspective, 5250 has a long future for system administration. But

it should be deprecated for application development. Also, any derivative
of the write-read paradigm (including OA handlers) should be deprecated in
regard to user interfaces - in my opinion.

Also, as Jon and Vern have suggested - put business rules as close to the
database as possible. For me, that means putting that logic in what I like
to call "database handlers", which are procedures named on_read(),
on_write(), on_update(), on_delete(), which are invoked by a generic
database trigger utility.
