RPG preamble To design the display:

• You can design a display within a 5250 environmentOr

• You can design a rich open display (mobile, browser, desktop)

In 5250 environment, the design possibilities are limited and a DDS format is directly produced for the display description.

In open environment, the design possibilities are wider as open formats can be used for the display description to incorporate rich UI elements and capacities.

DB 2. And Drag & Drop

fields…

…to directly design fields with their definition and also label onto the display.

Nope…but let’s say yes!

Or to charm anyone…

The RPG Dude

Could a solution exist?

Take a big breath!
