Re: XML to 5250

John,

Since the required flexibility is not available in DDS, it won't be in 5250
when you de-translate backwards..

My suggested approach - you write it in the lowest common denominator (green
screen - which you can do well) and you use a decent tool to webface it and
add the required flexibility (which I can do well)...
