Joe how do you handle the:
 We need both  web & green screen interfaces cases
       with you methodology?

Revitalization was designed from the beginning to support the original green
screen interface.  After modification, the programs STILL RUN as green
screen.  They can even be maintained as green screen programs.  The only
thing you'll see in your main code is that display file I/O opcodes are
replaced with calls to subroutines, like so:

PSC dC**                   WRITELINCTL01
PSC aC                     EXSR PSCI01

That's it.  If you don't actually have to change the screen I/O opcodes (and
95% of the time, you don't actually change the EXFMTs and WRITEs, you just
change the indicators and the contents of the field), then you can maintain
the program using SEU and it will work just fine.  If, on the other hand,
you do have to change how the screen I/O works, you simply run it through
the converter again - the conversion takes just a few seconds.

If you actually change the layout of the display file, obviously you may
have some work to do on the UI end, although my goal for next month is to
have at least a default user interface that can be used while you're
tweaking the pretty version.

My philosophy is that a company's largest asset is not only its legacy
programs, but also its legacy programmers, and the idea is to be able to
continue to test and maintain the original programs in their original green
screen mode.  If you use revitalization, the majority of your work can be
done by traditional AS/400 programmers.  No need to learn Java.

If you want pretty HTML, you can even contract someone to do that work, and
then plug it into the base stuff the tool generates.  That's a little more
involved, but the good news is you can do it at your leisure.  The goal is
for you to not have to learn any HTML to get the base panels working, and
then spend time on "prettification" for only those screens that make sense
from a business perspective.

Joe
