absolutely not !

and this is the way to go. No doubt about that. I fully agree with you. I'll
go one step further:
In all my application work I NEVER use ANY native features. All access to
screens, databases,
what have you, must be externalized through an interface. All my applications
have always
(since 1986) been fully portable and could run on any box. If you want to
access a customer
record you don't read it, you call the customer object handler which will use
SQL if it has
too, or IMS, or ISAM, or in memory data, or...
If you want to show a screen you invoke the screen handler, which will
generate 5250, 3270,
HTML, VT-100, Windows GUI, or whatever. The application programs never know.
This is a tried and tested way of doing it. Nothing new here. The vendors
hate it
("you mean you could run on my  competitor's box if he gave you a better
deal?").

So I laud your approach. Keep preaching the gospel, but go ALL the way. Don't
rely
on the AS/400 as the back-end. Then you are truly free.
