I've come to the conclusion that XML and the browser interface is the way 
to go. There are certainly differing opinions, but I've been working with 
it for about a month now, and it's really pretty slick. I'm using AVR based 
ADO modules connected to RPG server programs via ASNA's Datagate. No live 
operations experience yet, but it looks very promising. Very simple to 
implement. The client side validation and user interface is controlled with 
javascript which allows you to tap into all of the DHTML capability of IE 
as well as the rather nifty XML parser. User sequencing and filtering 
operations happen without a return trip to the server. There are other 
browsers, but fortunately for me, I don't need to contend with them, since 
it's all on the company intranet, all IE5+, and all using W3C published 
standard interfaces. Did I mention it's a lot of fun?
