I am guessing the link is done in the handler?

[Profound Logic]

Question:
I am guessing the link is done in the handler?

Answer:
What the handler does is take the field data populated by the RPG and then formats it for browser display at runtime when a display file output operation is done. Conversely, it will also take the browser input and feed it back into the fields in the RPG program when a display file input operation is done.
