Re: No 5250-based applications

Nathan,

I'd like to continue this discussion with you, if you have the time.
Specifically, I'd like to run through a couple of different application
examples, and get your feedback regarding how you'd handle them.

However, the discussion will now get into the nitty-gritty details of
writing a web-app, so we should move it to a different forum. WEB400 is the
obvious choice, but since the listserver will be down for a few days, or
maybe longer, perhaps we should pick this up on Ignite. What do you think?
