I don't see where you are doing this.  Are you?

No. That should be added. I just forgot about that.

Ok. At least now I know I'm not missing something. I have code that does this. I'll see if I can make it work with the stuff you've done.

btw - word wrap is a tougher problem.  I've done a proof of concept
program that handles it (the very first x5250 release).  We could use my
proof of concept code and integrate into tn5250.

No problem! I'm sorry, but I don't know what word wrap is. My knowledge

Word wrap is a special case continuous field where words are kept kept together and the lines break at spaces.

I think the single FFW variable is fine since according to the docs you
can only have one field format word for each field.  As for the continuous
flags, my implementation is not complete and I think we should use yours.
While what I had in mind for continuous fields would work, what you have
done better follows the 5250 protocol and thus would make more sense to
some future coder.
Sure. But I can't take the credit for the correctness of the code since I did have inspiration from the tn5250j project. I only had to understand the inner workings and reproduce it in C. Ohh... C, I still code in C!?! :)

Ok, I'll put together a combined field.h with these ideas. Then I will make field.c and session.c have our combined work and use the new field.h.

The only change I would make to your implementation is that it assumes
continuous fields all occur in order one after the other.  The way I did
cursor progression allows us to use continuous fields even if they are out
of order.
Ok, I can't recall but I assume you understand the problem better than me :) Anyway, we would have to add the content flow on "middle deletion" to the code. Did you implement that? I haven't looked at this.

I did implement this, but not in tn5250. I only have proof of concept code that I did for the very first versions of x5250. I'll see if I can make that code work here in tn5250.
