In my heart, I am in agreement regarding modernizing apps but there is a 
"CATCH-22" for AS/400 evangelists:  one of the big points made in 
marketing the AS/400 is it's ability to help a company retain it's 
investment in software.  So we need to be careful to balance our desires 
for progress against (at least one of) the strengths of our platform. 
 Lest I sound like an ultra-conservative "stick-in -the-mud" I have to 
admit that I am in the process of playing with Domino, learning Java, 
trying to convince certain folks to consider web-enabling their apps, 
etc.  I just wanted to present a little food for thought.  I also think 
I may have just set a new midrange-l record for cliches contained in a 
posting.  We're number one!
