Scott,

You are a light year ahead !

Have you wrote a book about the subject ? Or perhaps thinking about it ?

Regards

One of the great things about using UDTFs in that manner is that you can
write all of the business logic once, and put any sort of front-end you 
like on it.   Printout, Subfile, Excel document, HTML, GUI... anything 
you like without a re-write.

Most of the projects I do these days have both a 5250 and a web interface on
the same program.  That way, the folks who are lagging behind and resist
change can still use the 5250 approach.  The majority of our users, however,
get the improved UI of a web interface.

It's been my opinion for many years that folks need to make sure they're
keeping their UI interface logic separate from their business rules.
